Setting the system date and time is fairly easy on solaris. Because you can easily set the time from the command line, you can set the time on a server remotely.
sudo date mmddhhmmyy
The date command takes the syntax mmddhhmmyy, or “month day hour minute year”. You have to be superuser to set the time.
# sudo date 1201010106
