Sometimes you need to know if your computer has the correct time, what do you do to ensure that?
On Windows XP you double click on the clock in the right corner of your screen select "Internet Time" and click "Update Now". All the times I did this I got an error. Windows has only two entries in that combobox, and both return errors, why?!
Today I have gone a step further I googled for more Internet Time Servers, on this page I've found plenty. For example Germany has 214 servers in a time server pool (de.pool.ntp.org).
It was about time ;-)
