Almost looks like an IP address.
People only suggest GMT because it is global time and used as a
reference to all time zones. You can also refer to GTM as UTC (as they
are both the same).
SETI@home uses UTC, they even have a
UTC Time Conversion page. So why not other international sites (which Channel9 is).
To prevent ambiguity you could always use dd-mmm-yyyy (i.e. 21-Jul-2004)
The thing with localisation is often that Windows users still have it
set in US format (DD/MM/YYYY), and code that checks the browsers
location often gets 'en-US'. It would be good if Windows CD's bought in
the UK where set to British Summer Time rather than Seattle. I wonder
how many PC's are incorrectly set up due to this?
