Either the NBS website or Telecharge (can't remember which for sure) lists the run time as 1 hour. So even with a 5 minute hold you'd be out by 7:05ish giving you about 50 minutes to get from Theatre Row on 42nd (a couple blocks West of Times Square) to 44th on the opposite (East) side of Times Square. For you to judge based on how quickly you walk. LOL!
