Data4 is equivalent to system $RunTime, which is divided into time data 1, minute data2 and second data3. The steps are as follows:

Set data 1, data2 and data3 to switch type, so that data 1, data2 and data3 are equivalent to integers, and there will be no decimal part in division.

Do the calculation and work out the hours and minutes.

Hope to adopt. . .
