Fixed #7743: Reverted [8483], which was itself a reversion of [8481], after confirmation from Malcolm. Corrected a long standing mistake in the timesince/timeuntil filters when using a parameter for 'now'. Thanks to Andrew Shearer <ashearerw@shearersoftware.com> for the report.

 the comparison point (without the argument, the comparison point is *now*).
 For example, if ``blog_date`` is a date instance representing midnight on 1
 June 2006, and ``comment_date`` is a date instance for 08:00 on 1 June 2006,
-then ``{{ comment_date|timesince:blog_date }}`` would return "8 hours".

 Minutes is the smallest unit used, and "0 minutes" will be returned for any
 date that is in the future relative to the comparison point.
