Skype: Error: Invalid argument to date encode

Since Skype 3.5.202-3.5.239 (Windoze) I've been seeing these Error messages: "Invalid argument to date encode" when I click on the tray icon or the User interface. It can be fixed (as mentioned in the Skype forums) by going into "Edit you profile..." and changing "Show my time:" to your Time Zone (e.g. GMT for UK, Lisbon etc) as opposed to leaving it set as "My Computer's".
