Try this on a new worksheet:
Format B1: hh:mm:ss
Format C1: [hh]:mm:ss

Put =a1 in both cells

Now put some times in A1 to see what appears in B1 and C1.

Try
13:00:00
18:00:00
23:00:00
38:00:00
43:00:00

And you'll see what those []'s do.

what exactly do brackets around the hours mean?

The below formula will convert decimal minutes-seconds into real time
hours-minutes-seconds. In the current example, the total time is 23:59:00
which is correct.

However, if I increase the minutes so that they total more than 24 hours,
my formula losses 24 hours.

Can someone help me modify my formula, so if cell A2 changes to 2 decimal
minutes, the correct total would be displayed as 24:01:00, instead of
00:01:00 ?


Example Formula
*****************
=TEXT((SUM(A1:A5))/1440, "hh:mm:ss")


Example Data
*****************

A
===============
1 200.00
2 0.00
3 39.00
4 800.00
5 400.00
