Broadcasting and timestamp are different kinds of prefixes.
Broadcasting makes it so you relay the Twitch chat (if you wanted to for whatever reason), the timestamp is the prefix you see on your own twitch messages.

The timestamp format is described here. It's really simple for time formatting, and if you want any extra words you just put them between ' '.

For example, if you wanted your messages to be similar to [Twitch] [14:41] someone: something, you could set the timestamp to ['Twitch'] [H:mm].
