Mostly, no. There were rumors that the real-time format of the series had been abandoned, in favor of a 12-hour format that would be a condensed version of a 24-hour day. However, the bulk of the series is still in real-time, with every 1-hour episode depicting an hour within the series.It is only in the final episode, 10 minutes before the end, that there is a flash-forward of 12 hours. As a result, the series starts at 11:00 AM, and ends at 11:00 AM the next day. It still encompasses 24 hours, but skips one block of 12 hours within it.
