How do i work out the world time on linux?

[petulia3478]

Note: This command exists on later version of linux. The command does not change the time or date, it only shows you the setting you need.

Man page: tzselect

There are tons of webinars these days and some of them do not give you the time for your area.

There are many of websites that can get you world times these days, but if you do not want to get away from the command line, A way of getting the world time is by the tzselect command.

My webinar is in New York and New York is on the Eastern part of the United States. I chose Americas, United States, and then Eastern (most areas). tzselect gives you the variable to set if you want to make the change permanent.

$ tzselect

You can make this change permanent for yourself by appending the line
	TZ='America/New_York'; export TZ
to the file '.profile' in your home directory; then log out and log in again.

Here is that TZ value again, this time on standard output so that you
can use the /usr/bin/tzselect command in shell scripts:
America/New_York
