Post From: Spreadsheet programming question - FRACTIME

I have a 5 minute chart with a spreadsheet study.

In column AN, I have this formula
=FRACTIME(A3)-FRACTIME(A4). I'm looking for the difference between the last two FRACTIMES.

Im getting the following results:

0.00347222222222221 row 3
0.00347222222222221 row 4
0.003472222210648135 <========= ...
0.003472222233796285 <=========
0.00347222222222221

0.00347222222222221

0.00347222222222221 appears to me to be the 'correct' answer and those 'hiccups' are where the sheet updates. I understand they are double float numbers and will be slightly different based on updates.

Could someone with better math skills please explain just how long the updates take and maybe a little on the time keeping in general.

Ive read all I can find on time keeping including the following but cant quite make sense of it.
