Today I spent multiple hours trying to debug a timezone issue in a codebase. The timezone I was testing with was Etc/GMT+4, which I had assumed was four hours ahead of GMT. Turns out, it’s actually 4 hours behind GMT 🤦♂️
GMT+4 would add 4 hours to Greenwich Mean Time though? That’s GET (Georgia Standard Time), so 10am (1000) GMT would be 2pm (1400) GET.
GMT-4 would be EDT (Eastern Daylight Time), so that 10am (1000) GMT would be 6am (0600) EDT. Also, Georgia the state is in that time zone funny enough haha
(For the most part. Timezones are really really complicated and you should probably just look up the offset for the specific city/region you want Everytime and use some other package for time stuff lol)
According to NIST, Eastern Time is UTC-4. And currently it is 5:04pm EDT, and in London (a city in GMT/UTC+0) it is 10:04pm. Which is 5 hours ahead (because America is dumb and has daylight savings).
Which is also backed up by your article. Americas/Indianapolis is the one I normally use since I’m in Indiana.

Yeah, you would’ve thought it would work that way. Regrettably, the standard timezone code of
Etc/GMT+4is actually GMT-4. WikipediaAccording to NIST, Eastern Time is UTC-4. And currently it is 5:04pm EDT, and in London (a city in GMT/UTC+0) it is 10:04pm. Which is 5 hours ahead (because America is dumb and has daylight savings).
