DESCRIPTION
    "Time::Moment" is an immutable object representing a date and time of
    day with an offset from UTC in the ISO 8601 calendar system.

    Time is measured in nanoseconds since "1970-01-01T00Z". In "Time:Moment"
    leap seconds are ignored. It is assumed that there are exactly
    "86,400,000,000,000" nanoseconds per day. "Time::Moment" can represent
    all epoch integers from "-62,135,596,800" to "2,534,02,300,799"; this
    range suffices to measure times to nanosecond precision for any instant
    that is within "0001-01-01T00:00:00Z" to "9999-12-31T23:59:59Z".

CONSTRUCTORS
  new
        $tm = Time::Moment->new(
            year       => 2012,
            month      => 12,
            day        => 24,
            hour       => 15,
            minute     => 30,
            second     => 45,
            nanosecond => 123456789,
            offset     => 0,
        );

    Constructs an instance of "Time::Moment" from the given components.

    Parameters:

    year
        The year [1, 9999].

    month
        The month of the year [1, 12].

    day The day of the month [1, 31]. The day must be valid for the year and
        month, otherwise an exception is raised.

    hour
        The hour of the day [0, 23].

    minute
        The minute of the hour [0, 59].

    second
        The second of the minute [0, 59].

    nanosecond
        The nanosecond of the second [0, 999_999_999].

    offset
        The time zone offset from UTC in minutes [-1080, 1080] (±18:00).

  now
        $tm = Time::Moment->now;

    Constructs an instance of "Time::Moment" that is set to the current date
    and time from the system clock in the system time zone, with the offset
    set to the system's time zone offset from UTC.

  now_utc
        $tm = Time::Moment->now_utc;

    Constructs an instance of "Time::Moment" that is set to the current date
    and time from the system clock in the UTC time zone.

  from_epoch
        $tm = Time::Moment->from_epoch($seconds);
        $tm = Time::Moment->from_epoch($seconds, $nanosecond);

    Constructs an instance of "Time::Moment" from the given *seconds* from
    the epoch of 1970-01-01T00Z. The optional parameter *nanosecond*
    specifies the nanosecond of the second [0, 999_999_999]. Fractional
    seconds is supported if the constructor is invoked with *seconds* only:

        $tm = Time::Moment->from_epoch(0.123456); # 1970-01-01T00:00:00.123456Z

  from_object
        $tm = Time::Moment->from_object($object);

    Constructs an instance of "Time::Moment" from the given *object*. If the
    given object is an instance of "Time::Moment" it's returned otherwise an
    attempt is made to coerce the given object to an instance of
    "Time::Moment".

    "Time::Moment" implements coercion handlers for the following object
    types:

    DateTime
            $tm = Time::Moment->from_object( DateTime->now );

        The given "DateTime" object must be within the supported date range
        and must have a time zone or a time zone offset from UTC, coercing
        from the 'floating' time zone is not supported.

    Time::Piece
            $tm = Time::Moment->from_object( scalar Time::Piece::localtime() );

        The given "Time::Piece" object must be within the supported date
        range.

    The coercion scheme is extensible and implemented as documented in
    Params::Coerce:

        $tm = Params::Coerce::coerce('Time::Moment', scalar Time::Piece::localtime());
        $tm = Params::Coerce::coerce('Time::Moment', DateTime->now);

    "Time::Moment" also implements a coercion handler from "Time::Moment" to
    "DateTime":

        $dt = Params::Coerce::coerce('DateTime', Time::Moment->now);

  from_string
        $tm = Time::Moment->from_string($string);
        $tm = Time::Moment->from_string($string [, lenient => false]);

    Constructs an instance of "Time::Moment" from the given *string*. The
    string must consist of a complete date representation and time of day
    followed by a time zone designator. The time of day may be reduced to
    hour of the day, the second of the minute may have a decimal fraction.
    The decimal sign can be either the comma [,] or the full stop [.]. A
    decimal fraction must have at least one digit and may have a total of
    nine digits, if the fractional precision is greater than nine digits,
    the value will be truncated.

    The following are examples of complete date representations and time of
    day representations:

    The time designator [T] may be in lower case [t] or replaced with a
    single space. A single space is also accepted between the time of day
    and the zone designator if the time designator is replaced with a single
    space. The zone designator may be in basic format even though the
    calendar date and time of day is in extended format. The UTC designator
    [Z] may also be in lower case [z]. The literal string GMT or UTC may be
    used as a UTC designator and may have an offset. Usage of these string
    representations is strongly discouraged as they do not conform to the
    ISO 8601 standard.

        a decimal number [00, 99].

    %d  Replaced by the day of the month as a decimal number [01, 31].

    %D  Equivalent to "%m/%d/%y".

    %e  Replaced by the day of the month as a decimal number [1, 31]; a
        single digit is preceded by a space.

    %f  Replaced by the fractional second including the preceding decimal
        point or by an empty string if no fractional seconds are present.
        This conversion specification permits use of an optional maximum
        field width [0, 9] where the default field width of 0 will use the
        shortest of the following representations:

            .fff        (millisecond)
            .ffffff     (microsecond)
            .fffffffff  (nanosecond)

        Example:

            $tm = Time::Moment->from_string('2012-12-24T15:30:45.123456Z');
            $tm->strftime('%f');    # '.123456'
            $tm->strftime('%3f');   # '.123'
            $tm->strftime('%9f');   # '.123456000'
    
            $tm = Time::Moment->from_string('2012-12-24T15:30:45Z');
            $tm->strftime('%f');    # ''
            $tm->strftime('%3f');   # ''

        %3f is replaced by decimal point and exactly three fractional digits
        (zero-padded on the right or truncated if needed) if fractional
        seconds are present.

        *This conversion specification is an extension to the "IEEE Std
        1003.1"
        <http://pubs.opengroup.org/onlinepubs/9699919799/functions/strftime.
        html>*.

    %F  Equivalent to "%Y-%m-%d".

OVERLOADED OPERATORS
  stringification
        $string = "$tm";

    The $string will be in one of the following representations:

        YYYY-MM-DDThh:mm:ss
        YYYY-MM-DDThh:mm:ss.fff
        YYYY-MM-DDThh:mm:ss.ffffff
        YYYY-MM-DDThh:mm:ss.fffffffff

    Followed by a zone designator in one of the following representations:

        Z
        ±hh:mm

    The shortest representation will be used where the omitted parts are
    implied to be zero. This representation is conformant with ISO 8601
    profiles, such as:

    *   RFC 3339 Date and Time on the Internet: Timestamps
        <http://tools.ietf.org/html/rfc3339>

    *   RFC 4287 The Atom Syndication Format
        <http://tools.ietf.org/html/rfc4287#section-3.3>

    *   W3C Date and Time Formats <http://www.w3.org/TR/NOTE-datetime>

    *   HTML5
        <http://www.w3.org/TR/html5/infrastructure.html#global-dates-and-tim
        es>

    *   XML Schema <http://www.w3.org/TR/xmlschema-2/#dateTime>

    The "to_string" method or the "strftime" format string
    "%Y-%m-%dT%H:%M:%S%f%Z" produces an equivalent string representation:

        "$tm" eq $tm->to_string;
        "$tm" eq $tm->strftime("%Y-%m-%dT%H:%M:%S%f%Z");

    The total length of the string representation is between 20 and 35
    characters (inclusive).

  comparison
        $integer      = $tm1 <=> $tm2;
    
        $boolean      = $tm1 == $tm2;
        $boolean      = $tm1 != $tm2;
        $boolean      = $tm1 <  $tm2;
        $boolean      = $tm1 >  $tm2;
        $boolean      = $tm1 <= $tm2;
        $boolean      = $tm1 >= $tm2;

SERIALIZATION
  Storable
    The serialized representation of a "Time::Moment" is a string of 16
    bytes that contains MAGIC (2 bytes), time zone offset from UTC (2
    bytes), the number of days from Rata Die (4 bytes), second of the day (4
    bytes) and nanosecond of the second (4 bytes).

    The total size of the serialized "Time::Moment" instance using "nfreeze"
    is 34 bytes.

  JSON
    "Time::Moment" implements a "TO_JSON" method that returns the
    stringified representation of the instance.

  CBOR
    "Time::Moment" implements a "TO_CBOR" method that returns the
    stringified representation of the instance using tag 0 (*standard
    date/time string*).

    See CBOR::XS, RFC 7049 Section 2.4.1
    <http://tools.ietf.org/html/rfc7049#section-2.4.1> and "eg/cbor.pl" for
    an example how to roundtrip instances of "Time::Moment".

  Sereal
    Sereal version 2.030 or later implements support for the generic
    serialization protocol "FREEZE/THAW".

  FREEZE/THAW
    "Time::Moment" implements a "FREEZE" method that returns the stringified
    representation of the instance and a "THAW" method according to the
    serialization protocol specified in Types::Serialiser.

TIME ZONES
    An instance of "Time::Moment" represents an unambiguous point in time,
    but it's not time zone aware. When performing arithmetic on the local
    date/time or altering the components of the local date/time it may be
    necessary to use a time zone to convert to the correct representation.

    "Time::Moment" is API compatible with DateTime::TimeZone and
    DateTime::TimeZone::Tzfile.

  Converting from instant time to designated time zone
        $tm = Time::Moment->new(
            year   => 2012,
            month  => 12,
            day    => 24,
            hour   => 15
        );
        $zone   = DateTime::TimeZone->new(name => 'America/New_York');
        $offset = int($zone->offset_for_datetime($tm) / 60);
    
        say $tm->with_offset_same_instant($offset); # 2012-12-24T10-05

  Converting from local time to designated time zone
        $tm = Time::Moment->new(
            year   => 2012,
            month  => 12,
            day    => 24,
            hour   => 15
        );
        $zone   = DateTime::TimeZone->new(name => 'America/New_York');
        $offset = int($zone->offset_for_local_datetime($tm) / 60);
    
        say $tm->with_offset_same_local($offset); # 2012-12-24T15-05

  The Effect of Daylight Saving Time
    The time zone *Europe/Brussels* has 01:00 UTC as standard time, and
    02:00 UTC as daylight savings time, with transition dates according to
    the European Summer Time
    <http://en.wikipedia.org/wiki/Summer_Time_in_Europe>.

        $zone = DateTime::TimeZone->new(name => 'Europe/Brussels');
    
        sub convert_from_instant {
            my ($tm, $zone) = @_;
            my $offset = int($zone->offset_for_datetime($tm) / 60);
            return $tm->with_offset_same_instant($offset);
        }
    
        sub convert_from_local {
            my ($tm, $zone) = @_;
            my $offset = int($zone->offset_for_local_datetime($tm) / 60);
            return $tm->with_offset_same_local($offset);
        }

    European Summer Time begins (clocks go forward) at 01:00 UTC on the last
    Sunday in March, in 2014 the transition date is March 30.

        $tm1 = Time::Moment->from_string('2014-03-29T12+01');
        $tm2 = $tm1->plus_hours(24);
        say convert_from_instant($tm2, $zone); # 2014-03-30T13+02
        say convert_from_local($tm2, $zone);   # 2014-03-30T12+02

    During the transition from standard time to daylight savings time, the
    local time interval between 02:00:00 and 02:59:59 does not exist. Local
    time values in that interval are invalid. "DateTime::TimeZone" raises an
    exception when attempting to convert non-existing local time.

        $tm1 = Time::Moment->from_string('2014-03-29T22+01');
        $tm2 = $tm1->plus_hours(4);
        say convert_from_instant($tm2, $zone); # 2014-03-30T03+02
        say convert_from_local($tm2, $zone);   # raises an exception

    European Summer Time ends (clocks go backward) at 01:00 UTC on the last
    Sunday in October, in 2014 the transition date is October 26.

        $tm1 = Time::Moment->from_string('2014-10-25T12+02');
        $tm2 = $tm1->plus_hours(24);
        say convert_from_instant($tm2, $zone); # 2014-10-26T11+01
        say convert_from_local($tm2, $zone);   # 2014-10-26T12+01

    During the transition from daylight savings time to standard time, the
    local time interval between 02:00:00 and 02:59:59 is repeated. Local
    time values in that interval are ambiguous because they occur twice.
    When "DateTime::TimeZone" converts an ambiguous local time it returns
    the numerically lowest offset (usually the standard one).

        $tm1 = Time::Moment->from_string('2014-10-25T22+02');
        $tm2 = $tm1->plus_hours(4);
        say convert_from_instant($tm2, $zone); # 2014-10-26T02+02
        say convert_from_local($tm2, $zone);   # 2014-10-26T02+01
