The time are sync with our located time expect the tz is WASUT. my question is there any specific time for Malaysia or Singapore ? or can i leave the timezone empty ?

After reconfigure timezone setting as below the time different problem was solved.anyway i dont know what is below setting refering to? What is "Etc" "/G" "MT" and "-8BST" refering to?

looks like a corrupt TZ setting in /etc/environment to me since "Etc" is no valid timezone abbreviation. do a "grep TZ /etc/environment" and restore the file from a backup if it shows this "Etc..." stuff.

If only this one application has its time off, an individually set TZ variable might best and you can leave the system default like it was before.

Can you "cat /etc/environment" and show us the output. The easy way to set your timezone is to use smit (System Environments); however, this limits you to the default timezones.

1. Find out what is the correct timezone abbreviation for Malaysia; e.g. MST ?

2. As root, change the TZ variable in /etc/environment to:

TZ=MST-8

3. Save, start a new session, and check the date. You need a new session, as the
Timezone only gets set at login.

According to timeanddate.com your timezone abbreviation is MYT. As a test add the following line to your .profile file.

TZ=MYT-8

Save the .profile, logoff, logon, and run date. Is the time and date correct? If it is, then edit /etc/environment to contain the same TZ.
