DATE(1) 						      General Commands Manual							   DATE(1)

NAME
date - print and set the date SYNOPSIS
date [-nu] [-d dst] [-t timezone] [yymmddhhmm [.ss] ] DESCRIPTION
If 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 -d and -t flags set the kernel's values for daylight savings time and minutes west of GMT. If dst is non-zero, future calls to gettimeofday(2) will return a non-zero tz_dsttime. Timezone provides the number of minutes returned by future calls to gettimeof- day(2) in tz_minuteswest. The -u flag is used to display or set the date in GMT (universal) time. yy represents the last two digits of the year; the first mm is the month number; dd is the day number; hh is the hour number (24 hour system); the second mm is the minute num- ber; .ss 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. Date takes care of the conversion to and from local standard and daylight-saving time. If timed(8) is running to synchronize the clocks of machines in a local area network, date sets the time globally on all those machines unless the -n option is given. FILES
/usr/adm/wtmp to record time-setting. In /usr/adm/messages, date records the name of the user setting the time. SEE ALSO
gettimeofday(2), utmp(5), timed(8), TSP: The Time Synchronization Protocol for UNIX 4.3BSD, R. Gusella and S. Zatti DIAGNOSTICS
Exit status is 0 on success, 1 on complete failure to set the date, and 2 on successfully setting the local date but failing globally. Occasionally, when timed synchronizes the time on many hosts, the setting of a new time value may require more than a few seconds. On these occasions, date prints: `Network time being set'. The message `Communication error with timed' occurs when the communication between date and timed fails. 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-saving time. Thus, if you use both UNIX and VMS, VMS will be running on GMT. 4th Berkeley Distribution March 24, 1987 DATE(1)
