Yay! Success. Everything seems to be working fine now. Because I had to use a *slightly* older version, and it may be missing some modifications brought in by mods, please report anything that isn't working right. I'll begin offline tests to try and see if I can get the proper time zones working in v2.6, as well as improve on the colors of the activity bar (I also want to change the spacing of the bar. I'll play around with relative positioning for that). I'm also veeeery curious on why there seems to be a blank slot in the theme selection page (from your profile page). Seems to be a bug, but I can't find any associated folders for it. But then again, I can't check the folders directly, so no clue. But it's not harming anyone, so it's low priority.
I decided against removing the time zone thing, since it seems to be harmless enough for now, and should work if you switch to the default theme, change your time zone, then switch back (tested, and seems to be working for me, though I can't confirm any other timezones. Anyone?).
Changes required for v2.6:
*Modify theme to allow the activity bar to appear on profile summary page.
*Modify theme to allow the advanced time zone selection to appear on profile look and appearance page.
*Fix the javascript in the clock to include proper language tag.
+Fix the image linking for the logo (unknown error makes me use weird relative paths that I have to update with each new release).
+Change the activity bar to be gradient colors that more closely relate to the theme.
