When I open in the morning, I go to Reports>Paid out> $.01 "Start of day" and this opens the drawer for counting. I count each slot of my cash drawer in the "calculator" screen of the point of sale. This adds each together to give me the beginnig count. If the register was counted correctly at the end of last night, I should have the correct opening account. If you wish, you can save this as a ticket, name it "opening count (date)," or what I do is select "Clear all items."
At the end of the day, I do the same thing, but choose "Paid in" $.01 and type in "End of day," counting each slot as before. I make note of this amount. then back in Reports, I click "end drawer" and if all is correct with the world, my amount should be correct. If not, I exit out of this screen and re-count. You can also set aside the cash for deposit at this time.
This way, opening and closing counts have timestamps. When the drawer is over for the day, the slip that prints has the opening and closing time. I also print the daily sales report after closing the register.
