# Events
Events are broadcast by the server to each connected client when a recognized action occurs within OBS.

An event message will contain at least the following base fields:
- `update-type` _String_: the type of event.
- `stream-timecode` _String (optional)_: time elapsed between now and stream start (only present if OBS Studio is streaming).
- `rec-timecode` _String (optional)_: time elapsed between now and recording start (only present if OBS Studio is recording).

Timecodes are sent using the format: `HH:MM:SS.mmm`

Additional fields may be present in the event message depending on the event type.
