I am trying to set up a spreadsheet to record staff flex-time. Formating to
record time produces errors when negative are introduced.

Hi

Set your spreadsheet to 1904 calendar (Tools Options menu) to display
negative time. (Note that dates will shidt 4 years 1 days off by doing
this).

HTH. Best wishes Harald

Hi James,
If you are trying to obtain the hours through midnight, you would have
to add 24 hours (24 hours = 1 day) to the end time.

C2: 22:00
D2: 06:00
E2: =D2-C2+(C2D2)

C2D2 is a logical test it returns True or False
or in arithmetic 1=True 0=False

It is still a correct value even if it doesn't show as such, so any further
calculations using that value will be correct.

If it is just to see it correctly, you could force it like so

=IF(B1-A1<0,"-","")&TEXT(ABS(B1-A1),"hh:mm:SS")
