There seems to be no negative time in Excel. There is a time
difference, 08:00:00.00 in your example.
See attached .xls sheet.

Hi Grant,
Time is modulo 24 hours. so -1 = 23 and -8 = 16. This won't
affect Paul's measurements since most of them are taken with increasing
time. :-) We might have a problem with a midnight run.
