Subject: Log the time at which newly noticed tracks are added to the database.
X-Git-Tag: 4.0~99
X-Git-Url: https://www.chiark.greenend.org.uk/ucgi/~mdw/git/disorder/commitdiff_plain/343c64f2e715864266edf041d31e59cbb0035532?ds=inline;hp=-c

Log the time at which newly noticed tracks are added to the database.
This will allow disorder-choose to add a bias in favor of those tracks
(cf defect 11).
