NetClock Component [IP*Works! V8]

Properties   Methods   Events   Configuration Settings  

The NetClock component provides the current (GMT) time from an Internet Time Server.

NOTE: What follows is a very short description of the component interfaces. For more information, please consult the help files that come with the respective package.

Remarks

The NetClock component implements a standard Time Protocol client as specified in RFC 868, as well as an SNTP Protocol.

The address of the Time Server is provided in the TimeServer property. You get the time by calling the GetTime method.

The component also allows you to synchronize your system time with that of the TimeServer. This is done through the GetAndSetTime method. Calling GetAndSetTime will request the time from the server and then set the system clock to match it.
