here's a fun and easy one, I just ain't smart 'nuff

[Skidood]

Hi there...see below that I am computing the time interval from a series of timestamps. If the series covers midnight, I get a negative value which screws me up. How can I get a column matching the blue one? Note, there are 1440 minutes in a day.

Also, other sets of data used in this spreadsheet may not include 12 midnight...I appreciate your help!
