DATE(1) General Commands Manual DATE(1)
NAME
date - print or set the date
SYNOPSIS
date [ yymmddhhmm [ . ss ] ]
DESCRIPTION
If no argument is given, the current date and time are printed. If an
argument is given and the user is the super-user, the current date is
set. yy is the last two digits of the year; the first mm is the month
number; dd is the day number in the month; hh is the hour number (24
hour system); the second mm is the minute number; .ss is optional and
is the seconds. The year, month and day may be omitted, the current
values being the defaults. The system operates in GMT. Date takes
care of the conversion to and from local standard and daylight time.
The options are
-u Set or report GMT rather than local time.
-n Set or report the date as the number of seconds since the epoch.
EXAMPLES
date 10080045
Set the date to Oct 8, 12:45 AM, local time.

DIAGNOSTICS

version' if the date is invalid.
