Server Date and Time

Linux and Unix-Like Red Hat
1

Hi,
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.

To stop

 
service ntpd stop

To start

 
service ntpd start

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)

check is there any cron setup to synch the time for every 30 mins

i checked the cron jobs and this is what i got. Do you see anything that is changing the time?

[weblogic@sdpsb01 ~]$ crontab -l

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)
