Streamers often say put the time of events in their stream title
E.g. "Twitch Rivals Finals 20:00 PST"

The time should automatically convert to the the viewers local to e.g.
E.g. "Twitch Rivals Finals 02:00 GMT"

This can be done by adding auto detecting date formats and converting them to the viewers local time, or by allowing the streamer to add a "time element" in the title which allows them to specify when they are adding a time

Twitch is a very global and time relative platform, this just makes sense
