While I agree that entering a lot of time values can be a real pita,
entering the values as you want to do will usually make things much more
complicated than you think. For example, if you need to base calculations on
these entries. You had something that was relatively easy to calculate and
turned it into something much more complicated.

So, do the benefits of entering 100 as opposed to entering 1:00 AM outweigh
the complications?

IMHO, they do not!

What you could do is enter the time as 100 then have Excel automatically
convert that entry to a true Excel time value.

I would like to create a timetable in Excel with the format in the 24 hour
clock without the colon, which I believe is known as military time. I am
leaving the colon out for a number of reasons, aesthetic and to speed up
entry.

I wish to enter the time, for example, 8:30 am as 0800 and have Excel
interpret it as a time, as these will be graphed, so need to be
interpreted as time, and not plainly a number. At the moment Excel simply
shows "800" when I type 0800.

I have tried formatting all the cells as Custom "hhmm" instead of "hh:mm",
but when I enter the time data, it simply shows as 0000 and clicking on
the cell shows the formula of "dd/mm/yyyy hhmm".

Any ideas?
