WGT/WGST seems to be a widely accepted abbreviation for the West Greenland Time zone.
As far as I can see, it's an invented abbreviation propagated from tzdata, and there isn't much independent support for it. I've been trying to omit these inventions, as tzdata should record timekeeping not invent it.
I totally agree. I just never thought this was something invented or unofficial - I've always used these. I have gathered a few sources that mention WGT/WGST, but I honestly have no clue if these are based of off tzdata (which could very well be the case) or something else.: https://www.timeanddate.com/time/zones/wgt https://www.worldtimeserver.com/time-zones/wgt/ http://www.prokerala.com/travel/timezones/Western_Greenland_Time http://www.datetime360.com/timezone-wgt/ https://www.worlddata.info/timezones/wgt-west-greenland-time.php In any case I can't help feeling, that with all this "knowledge" out there, removing the WGT/WGST timezone abbreviations from tzdata seems wrong. These are the TZ abbreviations that we work with on a daily basis up here (I'm in Nuuk, Greenland) and suddenly they are unknown in our favorite timezone data. So I'm more inclined to try to somehow make these abbreviations official. I just need to know where to start.
the removal causes certain things to go belly up
Which things went belly up? Details might be helpful.
From what I've seen, PHP (on Ubuntu) had some hiccups and started mentioning Sao Paolo in my date/time outputs, because WGT/WGST was suddenly missing:
https://bugs.launchpad.net/ubuntu/+source/tzdata/+bug/1734967 A few of my own scripts that convert time between timezones started misbehaving as they expect WGT and WGST to be valid abbreviations. This is easy to fix, but there could be (and probably is) other places where this could cause problems. /Thomas
