I don't see an ss to refer to so the below is conservative.
My $0.02-
I would choose 1.5 hours late and gradually return back to desired shot time by shooting 15 mins early each cycle for the next 6 cycles or 30 mins early once each 24 hours for the next 3 days. Shooting early can set the stage for unexpected lows.
Have you started a ss yet? TR or SLGS? Shooting early acts like an increase. Shooting late as a decrease but can work. The following shot would need to be no more than an hour early the next cycle. I don't have enough info to say what I would do.
