With future time in A1, use =B1-MOD(NOW(),1) to find the time between then
and now. Might need to format the cell with [h]:mm
NOW returns the date and the time. Excel stores this info as a serial number
starting with 1/1/1900. Days are the integer part, while time is the
fractional part; MOD(x,1) returns the fractional part of x.

I want to use the now function to calculate elasped time. For example, I
leave work at 3:45pm Using the now function, what is the difference
between
the current time and when I have to leave?
