Examples

#import "std/chrono"
using chrono

dim as TimeSpan a = TimeSpan( 1, 0, 0 )
dim as TimeSpan b = TimeSpan( 0, 30, 0 )

print a.Add( b ).ToIsoString( )          '' PT1H30M

'' IMMUTABLE -- a new value comes back and the receiver is untouched
a.Add( b )
print a.ToIsoString( )                    '' PT1H, unchanged

'' Overflow yields Invalid; it never wraps
