Of course Etc/GMT-4 would be the most generic form.  (note the inverted sign is deliberate)

AZT-4 will work for POSIX compliant systems, but not necessarily with all systems.  I'm not 100% sure but I don't think it would work in Java, for example.

Subject: [tz] Azerbaijan canceled daylight saving time

Thanks to everybody who sent in a heads-up about Azerbaijan. Release
2016c of the tz database (released today) has an update for Asia/Baku
that should bring it up to date. Please see:


Although 2016c should eventually propagate into the systems that use the
tz database, this propagation process may take a while. As a temporary
workaround Azerbaijani users can set the time zone to some other value
in order to have computer-based clocks work correctly for time stamps
after this weekend. Possible TZ settings include 'AZT-4', 'Asia/Dubai',
'Asia/Tbilisi', 'Asia/Yerevan', and 'Europe/Samara'.
