I think the date code works as expected, and by design. It's just that
the code is a little confusing. :) Something like %(committerdate) gets
a used_atom with FIELD_TIME, and the "grab" function sets v->value to
the unix-epoch timestamp. And then the comparison function uses
v->value, since it's not FIELD_STR.

It's a little hard to follow the code that fills in v->value, but the
call stack is roughly grab_values() -> grab_person() -> grab_date().
