1)
Solaris:
The
fastest way to set the date and time in Solaris is by using the date command
while being the super user (root user).
date
mmddhhmmyy
The
date command takes the syntax mmddhhmmyy, or "month day hour minute
year".
Example:
date
012112052009
Wed Jan
21 12:05:00 IST 2009
Category:
Sun
And the
fastest way to set it to the right time would be to use ntpdate(1M) if one has
an ntp server.
2)
RedHat:
Run the following command as super user
date --set="Mar 18 15:14:00 2014"
