Jakub,

Thanks for the update.  This UI does seem to work better than the
original "[+]" dropdown interface.

The new code appears to degrade gracefully on IE6 (everything shown in UTC).

Tests on Firefox 3.6.15 looked OK.

Chromium 6.0.472.62 (59676) does not like this operation:

Uncaught Error: NOT_FOUND_ERR: DOM Exception 8
  removeChangeTZForm
  /gitweb-static/gitweb.js:785
onTZFormChange

line 785: var removed = container.removeChild(container.lastChild);

Opera 10.63 resets target.selectedIndex to 1 after calling
removeChangeTZForm() from onTZFormChange().  Net effect is that you're
always stuck in the "local" zone.  Here is a workaround that fixed it
for me:

       var target = event.target || event.srcElement;
       var selectedIndex = target.selectedIndex;

       removeChangeTZForm(documentFragment, target, tzClassName);

       var selected = target.options.item(selectedIndex);

Couple other random nitpicks:

If I delete my gitweb_tz cookie, then refresh the page:

 - All times show up in my browser's local time (good)

 - Clicking UTC/GMT on the dropdown has no immediate effect; I need to
   refresh the page again to see the times change (bad)

Should this hard-code class "datetime", or use $datetime_class from
the gitweb server configuration?

Might want to reword as "JavaScript-based"

Hmm, only 7 days?

"installs"
