ls to show dates and times in UTC
How do I get the ls command to show its dates and times in UTC, instead of localtime?
I don't want to permanently change the local time for my system to do this.
Solution 1:
One can set the time zone environment variable for each invocation of ls like so:
TZ=utc ls -l
or set it once with:
export TZ=utc
in a shell to have it always on, for the remaining duration of the shell session.
Solution 2:
To force UTC, set $TZ to UTC:
TZ="UTC" ls <options>
This will set $TZ to UTC just for the duration of this command.
