GetDurationFormat/StrFromTimeInterval equivalent

[Mike Gleason jr Couturier]

Hi,

Before writing out my own (buggy) function,

I would like to know if there is a .NET built-in function to display
a formatted/localized time duration?

ex.:
- 338 h 45 m 12 s
- 1 min 14 sec
- 3 days 4 hours

Thanks!
