Comment 4 for bug 1576742

It works for me.

I put the template {pubdate:format_date(yyyy)} in a column built from other columns, sorted the library by pubdate, and all the dates work. See the attached screen capture.

I am not saying it isn't happening to you, but I can't fix it until I can repeat it.

Have you set any of the tweaks that control dates, for example "gui_pubdate_display_format"?
