Creating a LocalTime from a TimeSpan should be simpler than it is

[GoogleCodeExporter]

While a TimeSpan really *isn't* a time of day, bits of the BCL treat it that 
way. It would be appropriate to have LocalTime.FromTimeSpan with appropriate 
caveats, and also LocalTime.FromTicksSinceMidnight and 
LocalTime.FromSecondsSinceMidnight. The current workaround is:

    LocalTime.Midnight + Period.FromTicks(ticks)

which is pretty nasty.
