Below is a Visual Basic statement that someone in this
NewsGroup gave to me a few weeks ago. I used it and I
now am able to enter the time as 0800 and have it appear
as 08:00 in cells formatted as hh:mm
You can then use a formula to subract one time from
another to calculate the duration. So 16:00 hours minus
08:00 hours will return an answer of 8 hours. Remember,
if your answer will exceed 24 hours, you must format the
answer cell as custom - [h]:mm
Should you wish to convert the answer to fractions of an
hour, format that answer cell as "number" with 1 or 2
decimal places and insert a formula that multiplies the
answer by 24. Thus an answer of 7:30 when multiplied byb
24 will return an answer of 7.5 hours.
