[PATCH v2 4/4] fix approxidate parsing of relative months and years

From
Jeff King <peff@peff.net>
Date
Aug 31, 2009, 02:31 UTC
Message-ID
<20090831023142.GD5507@coredump.intra.peff.net>
In-Reply-To
<20090831022228.GA4833@coredump.intra.peff.net>

These were broken by b5373e9. The problem is that the code marks the month and year with "-1" for "we don't know it yet", but the month and year code paths were not adjusted to fill in the current time before doing their calculations (whereas other units follow a different code path and are fine).
