Hello. In an application I must handle the duration of working hours of some users. I can handle these values in two ways:
1. Inserting "Start (hh:mm)", "End (hh:mm)" and then calculate the difference (hh:mm) between these values (Example A)
2. Inserting the duration expressed in minutes (Example B)

If a classic report in Apex the option "Compute SUM" for a numeric table's column would give me the sum expressed in a numeric value, for example 1130 that equals to 18hh 50mm but I need to show this sum expressed in hh:mm as you can see in the two examples above. Is it possibile to do this in the report?
Thank you for your help
