DATE(1)DATE(1)

NAME

date, clock – date and time

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 suffix.  

-f

Print using the format specified by the format string rather than the default. Format strings are in the format 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.
