Sean McArthur 7ddf8cb0e0 libtime: alter strftime to use a TmFmt ... The internals of strftime were converted to use a single formatter, instead of creating and concatenating a bunch of small strings. This showed ~3x improvement in the benches. Also, since the formatted time may be going straight to a Writer, TmFmt was introduced, and is returned from all formatting methods on Tm. This allows the saving of another string allocation. Anyone wanting a String can just call .to_string() on the returned value. [breaking-change]		2014-11-07 17:49:40 -08:00
