When logging in to remote machine X, by default, date
will give the time in the local timezone:
$ date
Mon Nov 17 22:45:47 CET 2014
Note that TZ
is not set:
$ export | grep TZ
$
So, I set TZ
to my own local timezone for every machine I'm on:
$ export TZ=/usr/share/zoneinfo/Canada/Eastern
$ date
Mon Nov 17 16:46:13 EST 2014
The question is, once I have this set, how do I get the time for the system default timezone, i.e. the timezone that applies if I, as a user, do not manually set TZ
? Unsetting TZ
gives me the UTC time, which is not what I seek:
$ TZ= date
Mon Nov 17 21:47:13 UTC 2014
Interestingly, TZ= date
gives UTC time, even when I didn't yet set TZ
to anything; yet when I didn`t yet set TZ
to anything, a simple date
gave the date in the system default timezone…

Try unsetting the
TZ
variable (which is different from setting it to""
):Note how I tried it in a subshell, so that my current shell remains unaffected.
