There is no possibilty to sort playlist by date. It wouldn't be realy necessary if i could sort the files by date before i add them to the playlsit in VLC's internal file browser.
Thank your for correction of my first post.
+1 for this. I believe the original author intended for allowing directory listings to be sorted by creation time (st_ctime) of the individual files in the directory. Last modification time (st_mtime) could also be used, but does not make much sense for media files. In the context menu from the screenshot posted above, an entry for "File age" will hence be added.
