Description:
When I type in certain times they get changed to a lesser time, i.e. 0:13 gets changed to 0:12 (0:12:59.99). But only in certain times and formats.

0:13, 0:26, 0,33, 0:49, and 0:52. I only went from 0:01 to 1:00

Formatted       Customized   Event
To              To           Occurred
01:37 PM                     No
13:37                        No
13:37           [H]:MM       Yes but only 0:26
876613:37:45                 Yes
876613:37                    Yes
876613:37       [H]:MM       Yes *
876613:37:45.99              Yes
876612:37       [H]:MM       Yes

Using the format with the * I did:

row 1  0:01
row 2 =sum(h1+"0:01")

Then copied it down to 1:00. it repeated 0:12 (row 12 and row 13)got errors this was also.

It happens on any spread sheet in any location in a spread sheet, and on three different computers.

I saved a copy if the table I made as an HTML and posted it to:
