XP is still up to date with timezone changes as far as I am aware but
you will need to ensure all (including optional) updates are
installed, and that may only be possible with an enterprise support
contract now.

If all else fails, you can disable automatic timezone updates with the
following registry key:

DisableAutoDaylightTimeSet REG_DWORD (1 = disable daylight-savings
adjustment, 0 or not set = enable adjustment)

Not sure if third party software can keep you in the right zone then,
but I'd imagine so.

Really though the correct fix is to upgrade to Windows 7. It's stable,
works well, and will be supported for years to come; though if you
want long term stability/updates you're better off looking into Linux
