37 minutes? That they noted the exact time isn't necesarily unusual. It's not unusual for crews have elapsed time, or time remaining, running on timers, clocks, or their wristwatches, and to be aware of the time.
Eg, saying goodbye to passengers last trip and a F/A's watch alarm went off - "that's when we were supposed to land". She set a countdown timer because they had certain services to start with X time left.
When giving written reports sometimes the times I report are close estimates and sometimes the times are exact. It just depends if I, for whatever reason, was able to recall exactly when an event occurred.
