SCTE 35 Part 2
elapsed
event_descriptor · Time100us
How long the event has already been running at this point, counted in 100-microsecond units, so 10,000 units is one second. Together with remain it lets a receiver place itself inside an event even if it missed the original start message. The all-ones value 0xFFFFFFFFFF is a sentinel meaning not applicable or not indicated, for example before the event has started, and is not a real elapsed time.

Standards note
Besides the 0xFFFFFFFFFF not-applicable sentinel, an elapsed of zero (0x0000000000) is conformant only when event_state is start; an elapsed of zero in the active, paused, resume, or fetch state is nonconformant.
