Server Date and Time

I am trying to change server date and time for testing purposes but every time i change the date and time it gets switched back to system date and time after half an hour or so. Is there a way to change the server date and time temporarily? My guess is that the server time is in sync with time server.

Server Date and time

Thanks for your reply. I stopped the ntpd service but i can still see in the log that after about 26 minutes, time changes back to current time. I am trying to change the server date and time on my development server to september 7, 2010 for testing purpose(i have pasted a portion of the log below)

cek your /etc/ntp.conf configuration and see whether is it pointing to any specific ip address.. and you can disable the synchronization from the time clock if u use gui just click the time in the taskbar and later u untick the sync(there are 2 radio button at the bottom)
