The Fn rtime function consults the Internet Time Server at the address pointed to by Fa addrp and returns the remote time in the Vt timeval struct pointed to by Fa timep . Normally, the UDP protocol is used when consulting the Time Server. The Fa timeout argument specifies how long the routine should wait before giving up when waiting for a reply. If Fa timeout is specified as NULL however, the routine will instead use TCP and block until a reply is received from the time server.
