Technically speaking, the TZ variable requires a leading colon when
specifying a file.  So the above example has to be:

:; env TZ=:Etc/GMT-2 date
Sat Jul  7 06:29:14 GMT-2 2007

Many libs try looking for a file even without the leading colon, but
that is not part of the standard.

Cf: tzset(3), such as at:
