User should see a reminder when somebody is in a different time zone and likely asleep

[holmesworcester]

Use case: a group of journalists are working spread out over many time zones.

They have a mutual expectation to be responsive in pretty much any of their waking hours. Often when someone is in a radically different time zone they wake up to a ton of frustrated messages from somebody, followed by some messages describing the person's realization that they were actually in another timezone all along.

The best solution seems something like the bot notices that Slack gives you when you message someone who is probably away.

Feedback:

• Journalism org opted for hard-coding the timezone alert hours to 9am-10pm
• We don't have to autodetect the timezone (it's tricky because there are two devices that might report different timezones) but having to remember to change the timezone manually seemed like it would be annoying. One solution is to ask users if they'd like to change their timezone and one user mentioned Notion as an example that does this well.
• We should probably remove the "autodetect timezone" checkbox for the reason that devices might disagree, but we could also have a prompt that displays only when devices disagree if that seems better.

I think we should autodetect based on the 'active' device at the moment and if it's different from a previously active device or location we provide that info to the user in a prompt. Something like "Would you like to change your timezone to your current location or keep your default setting" at the same time we can show what it will be set to based on their choice. Wdyt?
