The events come before the actual program start time so that there is time
to start the set-top-box or whatever device the stream comes from.
The number of seconds before the recording starts is part of the event
message so you can use that to select actions.
For instance, you can power on the set-top-box at 120 seconds and then
start the recording at 30 seconds before the program start time.

Hope this helps,
Klaas.
