Billy Keyes d3116e7b7e Make patch date parsing simpler and stricter (#15)
Removed the distinction between parsed and raw dates and simply return
an error for unsupported date formats. Arbitrary date support was
probably a premature optimization and would be better supported by a
method to register custom date parsing functions.

Simple time.Time fields make the structure easier to use and mean that
a zero value always indicates the patch did not include a date.
