Calculate time up to midnight

[tarork]

I have a list of date and time stamps where I'm calculating the difference. All was well until some dates a missing. So time stamp of 8/1/2019 1:10 PM, then the next time stamp is 8/3/2019 6:30 am. The person obviously took a day off and in some instances takes 1-2 weeks off. We need to find 24 hour intervals so I'd like to find the time from 8/1/2019 1:10 PM to 8/2/2019 00:00:00. Or whatever midnight of 8/1/2019 is to Excel. Been Googling for hours and everything is end time minus start time, but having difficult figuring out how to use midnight as the end time.

Thanks much,
tarork

If A1 is time stamp, i.e, "8/1/2019 1:10 PM"

=INT(A1)+1
is "8/2/2019 0:00"

And different time between both time:
=1-mod(A1,1)
format as "hh:mm"

Thank you for the quick reply bebo021999. I'm getting .45 as the difference in midnight minus 8/1/2019 1:10 PM. I expect to see 10.83 or something like that. =INT(A1)+1 gives me 8/2/2019, but when walking through the formula, it's just 43678 not 43678.000000. I'm using the integer of date/time because in the end I create a pivot table to sum all times for one day, which should equal 24 which tells us the date time stamps are correct throughout, or we can pinpoint issues when it is not. I attached a sample file. Thanks again for your help.

0.45 is the same as 10hrs and 50 min which seems correct to me as being the difference midnight minus 8/1/2019 1:10 PM ( to XL the underlying value for 24 hrs is 1)
and 0.67 is the same as 16 hrs and 5 min which again is correct?
I don't understand what is wrong?

I got it figured out. Should be ((INT(A1)+1)-A2)*24. I was missing the function to change it to 24 hours so that I get 24 hours in the summary for each day.

Thank you! You pointed me in the right direction.
