问题
I'm trying to calculate the difference between two times that are given in this format:
Fri 07/02/2014 10:16 with the cell using a custom format ddd dd/mm/yyyy hh:mm
and display the result in hours.
I have two dates/times:
A1 B1
Fri 07/02/2014 10:00 Fri 07/02/2014 10:42
The formula I have in C1 is
=TEXT(TIME(LEFT(RIGHT(B1,5),2),RIGHT(RIGHT(B1,5),2),0)-TIME(LEFT(RIGHT(A1,5),2),RIGHT(RIGHT(A1,5),2),0),"h")
Which gives me the answer 4, which I thought should be something like 0.68
Can anyone help?
Thanks
UPDATE:
A1 is actually in this format 07/02/2014 10:00:00, which is then displayed as Fri 07/02/2014 10:00
B1 is entered as 'Fri 07/02/2014 10:42' and displayed as 'Fri 07/02/2014 10:42'

Please try:
=DATE(MID(B1,11,4),MID(B1,8,2),MID(B1,5,2))+(MID(B1,16,2)+RIGHT(B1,2)/60)/24-A1
and format the cell as [hh]:mm.

It should be sufficient to remove the day part from the string in B1, assuming that your default date format is dd/mm/yyyy then this should work in C1
=MID(B1,5,16)-A1
format C1 as [h]:mm

Dates and time are just numeric values, integer part represent date (number of days since 1900-01-01) and fractional part represents time. So as he have 24 hours in a day, and if you have valid time values, independent of the format, hours can be calculated as:
= (B1-A1) * 24
