This article describes how to use the TZ environment variable to set the time zone for a shell account.
By default, the Linux shell uses the host server's time zone. If you are located in a different time zone, you can change this setting by using the TZ environment variable.
The TZ environment variable affects file and directory timestamps, as well as output from the date command. The following example shows how to set the time zone for California using the TZ environment variable:
export TZ="/usr/share/zoneinfo/America/Los_Angeles"
To make the setting take effect for subsequent logins, you can add this line to the ~/.bash_profile file or ~/.bashrc file.
