i've discovered an odd bug when combining negative relative dates and fixed dates. with positive relative dates, it works fine:

"1d sep 1" => 2012/9/2

but if i used a negative relative date, it properly computes the difference, but then (inexplicably!) subtracts a year.

"-1d sep 1" => 2011/8/31
"-1w jan 15" => 2012/1/8

hopefully it's a simple fix to make this work as expected.
