Description

Out of create, send, receive and deliver, which timestamps should be recorded and later restored when replaying events?

One use-case reported by Johannes:

If one channel in a tide file is assumed to be the absolute reference for all other activities, all timestamps should be relative to the first event of that special stream. The first event there should have timestamp 0.
