TimeSpan *****alent for the working week

[C# Programming]

Hi all, I'm looking for a class that works like TimeSpan but only takes account of a specifiable working week, so that if you add 12 hours onto 9AM Monday it returns 1PM Tuesday, or if you add 12 hours onto 9AM Friday you get 1PM Monday for a 5-day week, 9-5 working day.

Does such a thing exist?
