[PATCH 0/2] accept non-integer for "this many days" expiry specification

About a month ago, we wondered why

	[gc]
		rerereResolved = 5.days

does not work and if we want to do something better.  

Here is a pair of patches that attempt to improve the situation.

Junio C Hamano (2):
  rerere: represent time duration in timestamp_t internally
  rerere: allow approxidate in gc.rerereResolved/gc.rerereUnresolved
