how do I format a cell to subtract 3 hours from another cell?

There's probably a more efficient way to do this, but I so rarely use Times
in my work, I'm not sure. But if you're just working with Time and not
Dates, this works:

=TIME(IF(HOUR(A1)<3,21+HOUR(A1),HOUR(A1)-3),MINUTE(A1),SECOND(A1))

Can't you just subtract 3 from the hour value?



Example. Say cell A1 has Eastern time. You want cell b4 to reflect
pacific time.

In cell b4 enter "=A1-3"


Or, you could just move to California.

Try something like this:

For a time in A1
B1: =A1-3*1/24

The cells must be formatted as Time to display correctly.

Does that help?

But you'll have a problem with this if, for instance A1 contains the
time 02:00

Try

=MOD(A1-"03:00",1)
