Subject: Use a renderer function on the date field
X-Git-Url: http://git.tdb.fi/?a=commitdiff_plain;h=fa2a6fb7639ea09c1571a7f8da9915ee1f9ab1eb;p=ext%2Fsubsurface.git

Use a renderer function on the date field

Instead of creatign an extra column containing the date text, use a
renderer function to create the text dynamically.

Just the date right now, but we'll do them all this way.
