Subtracting Hours

[Amnon Wilensky]

Hi,

I want to convert Israel time to U.S time. Every thing is going fine until
the number become negative. For example: if the time in Israel is 02:30 and
I want to find what is the time at New York I have to subtract 7:00 hours,
and I Excel don't calculate it.

Any help?

Thanks,

Amnon

if A1 = 02:30 and B1 = 07:00
then you can use:
=MOD(A1-B1+"24:00","24:00")
to get 19:30

Just use

=MOD(start_time-hours/24,1)

Try this

=A1-7/24+1 Format cell as hh:mm
