So just for additional context:

This meme was brought to you by the following API response scheme:

{
  "time": "2007-12-24 18:12",
  "servertimezone": "Europe/Vienna",
  "timezoneoffset": -8
}

when it could have just been

{
  "date": "2007-12-24T18:21:00-07:00"
}

It should be implemented in people’s brains.

How this goes, usually, is:

Them:…before 6PM.

Me: 6PM… Ours? The server’s? The user’s?

Them: GMT, of course.

Me: So that’s 7PM London right now, and changes to 6PM in November?

Them: What no are you stupid. Always 6PM GMT.

Me:* jumps off a cliff*

When the API returns UTC, but the system insists on giving you local time… but there’s an extension method that accepts DateTimeOffset?
