Get Current Date/Time from NIST Time Server

See more Socket/SSL/TLS Examples

Demonstrates using Chilkat Socket to connect to an NIST time server and (using the old Time Protocol (RFC 868)), will read the current GMT time.

Note: This is not necessarily the very best means for getting the current date/time. The most commonly used time protocol is the Network Time Protocol (RFC-1305).
