SYNOPSIS
date [ -unit ] [ -f format ] [ seconds ]
clock
DESCRIPTION
Print the date, in the format
Tue Aug 16 17:03:52 CDT 1977
Or the format specified by the format option.
The options are
-u Report Greenwich Mean Time (GMT) rather than local
time.
-n Report the date as the number of seconds since the
epoch, 00:00:00 GMT, January 1, 1970.
-i Report the date as ISO-8601 without time and timezone
suffix.
-t Report the date as ISO-8601 with time and timezone suf-
fix.
-f Print using the format specified by the format string
rather than the default. Format strings are in the for-
mat used by tmdate(2)
The conversion from Greenwich Mean Time to local time
depends on the $timezone environment variable; see ctime(2).
If the optional argument seconds is present, it is used as
the time to convert rather than the real time.
Clock draws a simple analog clock in its window.
