There is currently no way to specify an absolute time as a constant
(though see the current_time
and network_time
functions
in XXX). You can specify interval
constants,
however, by appending a time unit after a numeric constant.
For example,
3.5 min
denotes 210 seconds.
The different time units are usec
, sec
,
min
, hr
, and day
, representing microseconds, seconds,
minutes, hours, and days, respectively. The whitespace between
the numeric constant and the unit is optional, and the letter “s”
may be added to pluralize the unit (this has no semantic effect).
So the above
example could also be written:
3.5mins
or
150 secs
