Change Time Zone Environment Variable

TZ

The environment variable that should be set in order to change the time zone for the commands run from within the environment variable's scope is TZ.

The TZ environment variable is used to set the time zone for a command or a set of commands. The TZ variable contains information about the local time zone, including the name of the time zone and the offset from UTC (Coordinated Universal Time).

To set the TZ environment variable, you can use the following syntax:

javascriptCopy code
export TZ=<time zone> 

For example, to set the time zone to Eastern Standard Time, you can use:

javascriptCopy code
export TZ=EST 

Or, to set the time zone to Pacific Standard Time, you can use:

javascriptCopy code
export TZ=PST8PDT 

Note that the value of the TZ variable is specific to your location and time zone. You can find a list of valid time zone values in the tzselect command or by referring to the tzdata package documentation.

Once you set the TZ environment variable, any commands run within the scope of the variable will use the time zone specified in the TZ variable. To ensure that the variable is set for all commands run within the shell, you can add the export command to your shell's startup file (e.g., ~/.bashrc for the Bash shell).
