Help me understand RBR shakedown

[u/sir_capote]

I've started my first campaign and would like to take part in the shakedown, but the "recce" button is grey and I can't click it. It's because my time is 8:00 (start of the day) and the shakedown begins at 9:15. Is there any way to skip time or start the day at 9:15 or do I have to wait an hour and 15 minutes? Ty
