incorrect 'date added' for songs in playlists

[shape5]

This initially occured before i just updated to the latest version (1.0.2.6....).  I changed the date/time of my Mac in the system prefs for only a minute or so and then switched it back to "set date & time automatically" but every track i added to my playlists for the next several days displayed "now" in the date added field.  After updating, it now displays "in 24 days"...LOL... this is not good!  i organize chronologically and this creates a big mess.  This is obviously a bug.  Is there any workaround to fix this?  Tracks i now add display the accurate date/time though.
