[1mNAME
     [0mdate - print and set the date

[1mSYNOPSIS
     date [0m[ -n ] [ -u ] [ yymmddhhmm [ [1m.[0mss ] ]

[1mDESCRIPTION
     [0mIf no arguments are given, the current date and time are
     printed.  Providing an argument will set the desired date.
     Only the superuser can set the date.  The -_u flag is used to
     display or set the date in GMT (universal) time.  _y_y
     represents the last two digits of the year; the first _m_m is
     the month number; _d_d is the day number; _h_h is the hour
     number (24 hour system); the second _m_m is the minute number;
     [1m.[0m_s_s is optional and represents the seconds.  For example:

	  date 8506131627

     sets the date to June 13 1985, 4:27 PM.  The year, month and
     day may be omitted; the default values will be the current
     ones.  The system operates in GMT.  _D_a_t_e takes care of the
     conversion to and from local standard and daylight-saving
     time.

     If _t_i_m_e_d(_8) is running to synchronize the clocks of machines
     in a local area network, _d_a_t_e sets the time globally on all
     those machines unless the [1m-n [0moption is given.

[1mFILES
     [0m/var/adm/wtmp to record time-setting.  In /var/adm/messages,
     _d_a_t_e records the name of the user setting the time.

[1mDIAGNOSTICS
     [0mExit status is 0 on success, 1 on complete failure to set
     the date, and 2 on successfully setting the local date but
     failing globally.

     `You are not superuser: date not set' if you try to change
     the date but are not the super-user.  Occasionally, when
     _t_i_m_e_d synchronizes the time on many hosts, the setting of a
     new time value may require more than a few seconds.  On
     these occasions, _d_a_t_e prints: `Network time being set'.  The
     message `Communication error with timed' occurs when the
     communication between _d_a_t_e and _t_i_m_e_d fails.

[1mBUGS
     [0mThe 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-saving time.
     Thus, if you use both UNIX and VMS, VMS will be running on
     GMT.
