It looks like you question lacks on word: calculate what between two times? Duration, or what? What's the role of AM/PM? What's the problem?

Do you understand that it cannot make any difference: this is a matter of time formatting, not the time structure itself.

Hi !

TimeSpan t = date1 - date2;

with t you can translate result to Hour, Minute, Seccond, day, month, year through properties same as type.

Actually, date2 - date1. OP have actually done an equivalent operation, so it won't resolve the problem (even though using '-' operator is much more readable). I think the solution of the problem would be... coming to understanding that the problem does not really exist.

Solution 1

As long as you are working with DataTime you should be OK - so I guess your DTimeBeginWork contains only the time in some format and not the date?

That being the case, you either need to specify the date or assume the date is the next day if the endwork time value is less than the Beginwork time value...

e.g.

C#

if (DTimeBeginWork.Value > DTimeEndWork.Value)
{
    date2.AddDays(1);
}
