Topic #: 9
Question #: 75
Topic #: 9
Which environment variable should be set in order to change the time zone for the commands run from within the environment variable's scope? (Specify the variable name only.)
Suggested Answer:
TZ
Explanation:
The TZ environment variable is used to change the time zone for the commands run from within the environment variable's scope. It specifies the name of a time zone as defined in the /usr/share/zoneinfo directory or a custom time zone in the POSIX format12. The TZ variable can be set either globally in a shell profile file or locally in a shell session. For example, to set the time zone to America/New_York for the current shell session, one can use the following command:
export TZ=America/New_York
To verify the change, one can use the date command to display the current date and time according to the TZ variable. The TZ variable can also be used to run a single command with a different time zone without affecting the system's time zone. For example, to run the date command with the Asia/Tokyo time zone, one can use the following syntax:
TZ=Asia/Tokyo date
The TZ variable is useful for testing how applications behave in different time zones or for displaying the time in different locations34. References:
