What is this feature supposed to do? From what I see, it appears that you manually turn it on and off as the seasons change?

That's correct. Setting the timezone you're currently in does not regard the DST and therefore you can set it additionally. There was a discussion to read the clients local timezone settings using javascript and submit it on login. This would then overwrite your prefs for the current session. I think this would be a nice feature, probably the user should be able to enable/disable it in the prefs.
