Inserts EXT-X-PROGRAM-DATE-TIME tags in the output manifest at the interval that you specify. If you don't enter
an interval, EXT-X-PROGRAM-DATE-TIME tags aren't included in the manifest. The tags sync the stream to the wall
clock so that viewers can seek to a specific time in the playback timeline on the player. ID3Timed metadata
messages generate every 5 seconds whenever the content is ingested.

Irrespective of this parameter, if any ID3Timed metadata is in the HLS input, it is passed through to the HLS
output.
