Get the closest event ID to the given timestamp.
Get the ID of the event closest to the given timestamp, in the direction specified by the dir parameter.
If the server does not have all of the room history and does not have an event suitably close to the requested timestamp, it can use the corresponding federation endpoint to ask other servers for a suitable event.
After calling this endpoint, clients can call /rooms/{roomId}/context/{eventId} to obtain a pagination token to retrieve the events around the returned event.
The event returned by this endpoint could be an event that the client cannot render, and so may need to paginate in order to locate an event that it can display, which may end up being outside of the client's suitable range. Clients can employ different strategies to display something reasonable to the user. For example, the client could try paginating in one direction for a while, while looking at the timestamps of the events that it is paginating through, and if it exceeds a certain difference from the target timestamp, it can try paginating in the opposite direction. The client could also simply paginate in one direction and inform the user that the closest event found in that direction is outside of the expected range.

Construct a URL without creating a full-fledged job object.
This function can be used when a URL for GetEventByTimestampJob is necessary but the job itself isn't.
|
inline |
The event's timestamp, in milliseconds since the Unix epoch. This makes it easy to do a quick comparison to see if the event_id fetched is too far out of range to be useful for your use case.
