Question

I need a TimeSpan that takes into account working hours. Let’s say that if we configure the TimeSpan with an 8 hour day, two days should return 16 total hours instead of 48. Does anybody know of such a class?

Thanks.

Edit

I need the same functionality as timespan but with configurable day duration. Adding, subtracting,…, should work taking this into account. I tried to extend TimeSpan, but it’s sealed. Maybe I should go for some extension methods to implement this as Oded suggested (or something similar).

If you simply want to figure out each day as 8 hours, you can do this:

return TimeSpan.TotalHours / 3;

Update:

Now that you provided some more detail, I would suggest wrapping timespan with your own type – you can have an HoursInWorkingDay property in it which will allow you to configure the number of hours in a working day.

Have a constructor that takes a timespan and assign that to a private timespan that you can use for calculations:

public class WrappedTimeSpan
{
    private TimeSpan ts;
    private int hoursInDay = 8;

    public WrappedTimeSpan(TimeSpan origTS)
    {
        ts = origTs;
    }

    public WrappedTimeSpan(TimeSpan origTS, int hoursInDay) : this(origTs)
    {
        hoursInDay = hoursInDay;
    }

    public int HoursInDay { get;}

    public int WorkingHours { get { return ts.TotalHours / hoursInDay; }}
}

This can be extended to cater for any other requirements you have.
