Ground_measures_features updating time based on UTC

For the prize period we are going to make our submissions every week based on the dates in submission file, i.e: 2022-02-17, 2022-02-24, 2022-03-03, …

Also, the ground_measures_features.csv we be updated accordingly on those dates.

My questions are (during the prize period):
A) when exactly the ground_measures_features.csv will be updated based on UTC time zone?
B) Is the updated time always the same for all the weeks?
C) Is the deadline for our submission for each date (3-day window mentioned in the instruction) based on UTC?

Thanks
