"Double transition"
This is an alarm clock taken with a tripod, with about 3.5 seconds in the 11:59 PM position, then quickly moved to the final position in about 1.5 second's time, and left exposed for another 3 seconds at 12:00 AM. The actual time transition from 11:59 to 12:00 is during the physical transition as well!
