The options of the date command vary from OS to OS. This should work as the root user on most systems:
-u denotes the time you enter is in GMT or UTC timezone, which may not be the timezone you are actually using.
So, try:
assuming you don't want to change seconds.

This is a new one on me. We upgraded a system from AIX 5.3 TL 7 to 6.1 TL 7 yesterday. The app people notified us that their cron jobs weren't running at the right time. So I made a test cron entry and here's what I've found:

date
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.

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.
