Thanks for below, however this comes back to the problems i experienced as
described in my original post with a start date of 08/06/2007 08:43 and a
finsh date of 21/11/2007 13:00 shows as 14 days 4 hours and 17 minutes, when
it should be 166 days 4 hours and 17 minutes

Put your start date and time in A5 (for example) and end date/time in
B5.

Here's the formula:

=(IF(INT(B5)-INT(A5)<1,24*(MOD(B5,1)-MOD(A5,1)),((INT(B5)-
INT(A5))*24)+24*(MOD(B5,1)-MOD(A5,1))))/24

Format as Custom: d "days," h "hours," mm "minutes"

Many thanks for below, which works for that specific start and end date,
however when i have a start date of 07/11/2007 12:29 and finish time of
07/11/2007 15:00 it gives an error "#DIV/0!" value instead of 0 days 2 hours
31 mins ??
Nearly there though i think.

Once again your assistance is greatly appreciated
