Grabbing the Date and Time From a Time Server on the Internet

Looks like only the time zones applicable to the US, however a simple table of time zones and their +/- relation to Universal Time could easily make this into a capable International Time function, once you knew the user's current time zone. 

This interests me, because while I *could* depend on the system time I suppose, to datetimestamp entries in an SQL table, the user could simply change the system time and date manually to defeat what I was trying to do. Using Universal time gotten just before the update or insert statement would prevent tampering.
