Comparable Excel Formula?

[Lee Hunter]

The task is to calculate the elapsed time between two
values. The first is a scheduled time with no associated
date (1/0/00 13.20)i.e. the same time every day. The
second is an actual time with it's asociated date
(7/31/04 13:30). The difference is negative 10 minutes
or 10 minutes late

The formula which works in Access is:
Var: DateDiff("n",FormatDateTime(Date1,4),FormatDateTime
(date2,4))

Is there a comparable formula in Excel?

Maybe something like

=IF(Date1=MOD(Date2,1),"On Time",ABS(Date1-MOD(Date2,1))&
" minutes "&IF(Date1<MOD(Date2,1),"late","early"))

One difficulty in Excel is that Excel doesn't handle negative tim
easily or well. You can't use time number formats with negative tim
values. However, if all you want is the numeric result,

=Date1-MOD(Date2,1)

would work
