I usually do it through the System Preference panel for Date & Time, but I'd like a quicker way to do this if there is one.

Use the following Terminal command:
sudo systemsetup -settimezone timezone
For a list of valid timezone values, use sudo systemsetup -listtimezones.
To get the current timezone, use:
sudo systemsetup -gettimezone
-
5And just for the record, you can also get the current timezone by doing
sudo systemsetup -gettimezone. Commented Sep 8, 2014 at 13:25 -

1Sadly, this isn't working for me. It seems to change it (says
Set TimeZone: America/New_Yorkand returns exit code 0) but thensudo systemsetup -gettimezonereturns the previous value (Time Zone: America/Los_Angeles). Commented Sep 2, 2016 at 17:38 -
2To get timezone without sudo, use
date +"%Z %z". This displays something likeEDT -0400, the upper case z outputs the TZ abbreviation, lowercase the UTC offset. Commented Apr 3, 2020 at 17:08
Additionally:
Printing a random timezone:
ruby -e "puts `sudo systemsetup -listtimezones`.lines.sample.strip"
Setting a random timezone:
sudo systemsetup -settimezone (ruby -e "puts `sudo systemsetup -listtimezones`.lines.sample.strip")
Finding a timezone (e.g. containing "Los" in this case):
sudo printf ''; sudo systemsetup -listtimezones | grep Los

I wish I could upvote this for the random timezone trick. Alas, it does not answer the question, and should probably be a comment instead of an answer. Cool script though! Commented Jun 17, 2023 at 5:07
