This is why servers and military use UTC.

My dumb ass brain read this like 3 times wondering why waitstaff would be using UTC.

Yes, when you are comparing times across time zones, you can use UTC time. (UTC is essentially a more modern GMT, there are differences but only the nerds care.)
You will want to use all times in UTC. But be aware that when you do this, any times that are meant to be the same throughout the year will shift one hour due to Summer Time/DST. Not every region does summer time, and the ones that do start and stop at slightly different times. (And Southern Hemisphere countries do it in Northern Hemisphere’s winter.)
If that’s too inconvenient for you, or most of your users are in your country, an alternative is to explicitly state the chat hours in your local time zone, with the understanding that it will shift a hour vs. UTC twice a year, and anyone outside your country’s summer time rules will just have to deal with it.

Swatch internet time

I remember when this came out and never figured out what they were thinking.

congrats! you are old. how’s the debian install working out? Same as the last 20 years?

It was a pretty unique experiment in Decimal Time

As a web developer we almost always store times in UTC, we simply convert it to the user’s time zone while displaying it. I prefer to use the browser’s time zone when doing this, but it could also be a saved user preference or even determined by figuring out the geographical location of your IP address (not a fan).

There is, just use Hammertime.

There is Swatch Internet Time (.beat), which was invented to:
… simplify the way people in different time zones communicate about time, mostly by eliminating time zones altogether. It also does away with the division of the day into 12 or 24 parts (hours), then 60 parts (minutes), then 60 parts (seconds), then 1000 parts (milliseconds). Furthermore, there is no confusion between the AM/PM system and 24-hour time.
For example:

Reminds me of the French revolutionary calendar. It also did time decimally.

Even if multiple people are online at the same time: why is time inconsistent (the sun is up in one place while it’s dark in another), you can ask friends what time it is in where they live (internationally) but receive different responses based on their surroundings. This person states it’s 08:00 while you reply it’s 23:00 on the same day with one difference: they’re starting the day while you’re about to finish it moving to another.
This is the price of living on a oblate spheroid.

As others have said, using UTC is the most reliable solution to communicating times across time zones. Everyone only needs to know their own offset (which might change twice a year if their location uses DST). A handy way to mark times as UTC is to attach a “Z” as in 20:00Z, which is part of the international standard covering dates and times ISO 8601.

There is.
On the Internet it’s always 2am.
Onomatopoeia@lemmy.cafe 3 days ago
That would be meaningless for translating to anything else, such as the time zone where any participants are.
Which is why everything uses UTC/GMT and offsets for local time

It is easy:
You just have to flatten the earth, and already everybody is in the same time zone.

There’s lots, but just like everything, very few people actually can stick with and use them. Probably the thing that I think would be a logical feature in most chat programs, would be if say you put in your timezone into the client somewhere, then when you type a time you put some character before it like *3:30pm - the chat client could determine your timezone, put it in chat as UTC, and each recieving client could automatically convert it to their users timezone (and I suppose some kind of tag to make it so people know it is already translated to their timezone).

Yes. GMT is UTC, therefore if you have to work out what time it is in other time zones, you use GMT/UTC. Your application shows the time in your time zone (unless otherwise specified). Responses will also be shown in your time zone.
