But when you applying this function in you daily work, you may notice that it only works to calculate total hours less than 24 hours, if the total hours are greater than 24 hours, it cannot work normally and we may get an improper returned value.

2.Total hours is calculated incorrectly when applying SUM for A2 to A6.

Step 2: Select this cell, right click to load options, select Format Cells in the last section.
Step 3: On Format Cells panel, under Number tab, select Custom in Category list, in Type textbox type ‘[h]:mm’, after typing you can see in Sample section ’36:46’ is displayed. If your time format is hh:mm:ss in working hours, you can enter ‘[h]:mm:ss’ in Type.
