DATE(1)             UNIX Programmer's Manual              DATE(1)



NAME
     date - print and 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, the current date is set.
     _y_y is the last two digits of the year; the first _m_m is the
     month number; _d_d is the day number in the month; _h_h is the
     hour number (24 hour system); the second _m_m is the minute
     number; ._s_s is optional and is the seconds.  For example:

          date 10080045

     sets the date to Oct 8, 12:45 AM.  The year, month and day
     may be omitted, the current values being the defaults.  The
     system operates in GMT.  _D_a_t_e takes care of the conversion
     to and from local standard and daylight time.

FILES
     /usr/adm/wtmp to record time-setting

SEE ALSO
     utmp(5)

DIAGNOSTICS
     `No permission' if you aren't the super-user and you try to
     change the date; `bad conversion' if the date set is syntac-
     tically incorrect.

BUGS
     The system attempts to keep the date in a format closely
     compatible with VMS.  VMS, however, uses local time (rather
     than GMT) and does not understand daylight savings time.
     Thus if you use both UNIX and VMS, VMS will be running on
     GMT.
