NetClock Class
Properties Methods Events Configuration Settings Errors
The NetClock component provides the current (GMT) time from an Internet Time Server.
Syntax
ipworks.netclock()
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 class 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.
