What is the problem of obtaining Internet time?

What is the problem of obtaining Internet time? Delphi/Windows SDK/API
Http://www.delphi2007.net/DelphiAPI/html/delphi_20061204151729125.html
The source code downloaded on the Internet Prompts that the control cannot be found.

Can it be the simplest?
It also describes where to add the control and how to use it.

Can I divide myself ???

Unit
Nmtime

Description
The tnmtime component is used for getting the time from Internet time servers, as described in RFC 868.
