Setting of two time formats in one machine

Hi,

Is it possible to set the two time formats in a single machine. My machine time is in EST and the logs are in PST. What would be the issue, and how to make change of this.?

Timezones are normally set in the user environment, so there should be no issues, and to be on the safe side, you can use different userids for each process management.

The time difference is in the root user and the other users. How this is possible?

Please state which Operating System you are using.
In general you get differences if "TZ" is changed in a user's profile so it is different from the one set in /etc/profile .
See.

man 5 environ

I am using centos 5

Sorry I don't understand your question.

How is *what* possible?

Display of time is a type of formatting issue. The time is the same, only the TZ (timeszone) is different.
