Hi Carl

If your data always has the latest time in the second cell, then with early
time in A1 and late time in A2
=RIGHT(A2,2)-RIGHT(A1,2)+60
works for me

My time data comes in like so:

93555
93600

Difference of 5 seconds

103058
103101

Difference of 3 seconds

Is there a way to convert these trimes so that when they are subtracted, I
can get the correct difference ?

Thank you in advance.
