Usual spelling is Cox. (No, not me, not even a relative.)
More importantly, I don't see that you need to coarsen your data for a survival analysis -- unless the sheer size of the dataset is problematic.
It could even be that time of day data has a secondary bearing on survival...

Yes, these options worked out for me, thank you.
I am collapsing the data set to prepare it for a cox proportional
hazard model. Each data point already has a few variables (distance
to cover, distance traveled, snow depth encountered) with measurements
for each point that I can average together for each day before I make
the model.
