Re: System time need to be change
If you are moving your server's time _forward_ then there are few issues in doing so. You can simply do:
# date mmddhhmm
If you are moving your server's time backwards, you will want to stop all databases and time-sensitive applications before you reset the time and then restart them afterwards. You may even want to wait the delta time before you resume them.
You are probably not running NTP to maintain accurate time. You should most certainly set this up. There are a vast number of posts in the forum on this subject to guide you.

Re: System time need to be change
the reboot is not required, maybe you should consider to shutdown the application ( if some app such oracle .... is running ), before you change the time on the server.
configure ntp(d) for periodical synchronization, or use ntpdate -b (ntp_server).

Re: System time need to be change
> becasue we are using oracle database which is in clustered enviornment
You _really_ need to establish an NTP managed environment for accurate time. This is so easy to do. Even if you have to use a third server as a local time source, keeping the current cluster times synchronized is just part of your high-availablity strategy. Implement NTP correctly and you won't face this downtime again!

Re: System time need to be change
First let everybody know ( Database team, application team, your team) and create a change management request that you are doing this change.
this is very important if your applications are date/time oriented for the transactions.
also configure your ntp server.
