I thought 'sum' is correct, but you are right. 'sum' in Appendix E does
not fit for time.
So, I agree with you that we need a new cell_method 'count over days'.
'count over days'  means: The values of the indicator of
"mean/minimum/maximum within days"
for every day is counted.
'count' indicates that the result is a number(integer) and that looks
good for me.

Do we need a new ticket ? I hope it does not take so much time.
