On some distributions (for example, CentOS), the timezone is controlled by /etc/localtime file.

Delete the current localtime file under /etc/ directory

# cd /etc

# rm localtime

All US timezones are located under under the /usr/share/zoneinfo/US directory as shown below.

# ls /usr/share/zoneinfo/US/

Alaska          Arizona         Eastern         Hawaii          Michigan        Pacific

Aleutian        Central         East-Indiana    Indiana-Starke  Mountain       

Note: For other country timezones, browse the /usr/share/zoneinfo directory

Link the Pacific file from the above US directory to the /etc/localtime directory as shown below.

# cd /etc

# ln -s /usr/share/zoneinfo/US/Pacific localtime

Now the timezone on your Linux system is changed to US Pacific time as shown below.
