Remarks

Managing times

Case 1: Direct assignment
During a direct assignment (for example, Day.StartTime..Hour = n), the time must be included between 0 and 23. A WLanguage error occurs if the specified time is invalid.
The notation Day.StartTime..Hour = Day.StartTime..Hour + 5 may generate an error at run time.

Case 2: Operations on times
When performing operations on the times of the Time or Date items ("Date and Time" format), the change of time is automatically managed.
The addition or subtraction of hours automatically takes into account the change from hour 23 to hour 0.
Therefore, if an hour is added to:

a Time item corresponding to 23:35, the result will correspond to 0:35
a Date item (Date and Time format), the time and the date will be modified (a day will be added).

// Example on a variable
StartTime is Time = "2335"
StartTime..Hour++ // StartTime = 0035
StartDate is Date = "200411262335" // 26/11/2004 at 23:35
StartDate..Hour++ // 27/11/2004 at 00:35

Managing durations

If the number of hours in a duration is greater than 23:59, the number of days is automatically incremented.

// Example on an item
