Gnulib also supports MSVC, which interprets the TZ environment variable in its

   UTC0
   GMT0
   GMT+0
   GMT-0
would all be equivalent and portable. Can you confirm this?

All of them would use UTC (the first one with the abbreviation "UTC", the others with "GMT"). Other variants would work as well, e.g., "UTC-00:00:00". I usually use "UTC0" as it's simplest and most technically correct (GMT stopped being standardized many years ago).
