Any mention of launch time to the second?
Milliseconds would be even better.

There is a second burn at apogee as indicated by the SECO-2 (second engine cutoff) on the timeline below. Unfortunately, the press kit does not give the times of the ignition and cutoff, but they look to be about four minutes before the Blacksky satellites are deployed.
