You want the Time Category in Format Cells:Number. You can select the format
37:30:55, which will display 93:11:00, then choose Custom and delete the
seconds. The resulting customized category will look like [h]:mm and will
show hours and minutes but not seconds.

When I enter hours and minutes in a cell (example: 93:11:00) the formula box
shows 1/3/1900 9:11:00pm. How do you get the formula box to display 93:11:00?
Also, is there a way to display only hours and minutes (93:11) since I don't
work with seconds? Thanks.
