I would like to take the value in the cell and round it up to the
nearest 5 minute interval.
For example:
09:31:45.002 would round up to 09:35
12:09:22.004 would round up to 12:10.
Thank you in advance.
=ROUNDUP(A1*1440/5,0)*5/1440
formatted as hh:mm:ss.000.
Time is stored as a fraction of a day. So 1 hour is 1/24, 1 minute is
1/1440, and 1 second is 1/86400.
