Different ideas on what "3 months ago" should mean

[zostay]

I received an internal bug report today stating:

Today I discovered a bug related to the use of "3 months ago". In this case, the resultant dataset is for a single day three months ago (8/12/12). I would expect to see all payments for August.

Looking into the tests I see this case:

{
    description       => '3 months ago from June 15 is March 15',
    date_range_string => '3 months ago',
    as_of         => '2013-06-15',
    beg           => '03/15/2013 12:00AM',
    end           => '03/15/2013 11:59PM',
}

Clearly, the choice to make this a single day 3 months ago is deliberate. I don't know if there is a fix for this, but something to consider.

I'm currently inclined to leave the behavior as-is. In my mind, "3 months ago" refers to a precise point in time, whereas "last month" and "next month" more generally refer to the entirety of a specific month.

This is mostly because I use "[n] months ago" searches fairly often to review email and whatnot, so that may just be a personal bias. I'm going to leave this open for now in case anyone else has opinions on the topic. (This assumes that people use D::RP::EN, which is perhaps a bit of a stretch.)

I have no strong feelings any which way. I am but a conduit on this one.
