What are you trying to achieve? Accuracy really depends on what you are trying to build and there might be a far better way of building whatever you are trying to build.

But for this specific question, the proper way would be for you to take advantage of a [url=http://en.wikipedia.org/wiki/Time_server]Time Server[/url]. They are servers (many of which are public) designed to hold and distribute the current exact time using the network time protocol and so are pretty much designed specifically for synchronizing computers around the world. You'll never get the exact time due to latency, but implementations do predict the latency you are occuring (note that they only predict).

On Windows there is the Windows Time Service which you could take a look at. This is MS's implementation of the Network Time Protocol and can give you the exact time to within a few seconds. It's also included with Windows since Windows 2000. There are far better libraries out there on the net which will give you a far more accurate time. For use with Blitz you'd probably be best building bindings in C/C++ and then calling it from BB.

As a poor-mans alternative you could find one of the many 'what is the current time' websites only and have your app download the page (using BBs TCP functions) and then just strip out the time on the page. You then need to add on half the time taken between starting the request and receiving the page (this is a cheap way of accounting for the latency).
