The coreutils Texinfo manual e.g. says (with text coming from gnulib):

  
<https://www.gnu.org/software/coreutils/manual/html_node/Specifying-time-zone-rules.html#Specifying-time-zone-rules>

  A TZ value is a rule that typically names a location in the ‘tz’ database
  (https://www.iana.org/time-zones). A recent catalog of location names appears
  in the TWiki Date and Time Gateway 
(https://twiki.org/cgi-bin/xtra/tzdatepick.html).

and (quite often):

  See Section “Specifying the Time Zone with TZ” in The GNU C Library.

Other than that, I'd have a look at the 'timezone' (sometimes 'tz') package
installed on your local system.

Have a nice day,
