Comment 9 for bug 501221

Katherine Kerr (compiler of the royal book, which now contains the OP) has requested greater refinement on the date features - to allow last 6 months, not simply the year range.

This is probably superceeded if the other changes she has requested are implemented.

However, I think the provost of scribes is also likely to think in these terms sometimes, rather than a year range which currently in early June would require loading all awards 2010-2011, ie 17.5 months worth to get 6 months.
