rtime(3)
NAME
  rtime - Get remote time

SYNOPSIS
  #include <sys/types.h>
  #include <sys/time.h>
  #include <netinet/in.h>

  int rtime(
	  struct sockaddr_in *addrp,
	  struct timeval *timep,
	  struct timeval *timeout );

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

RETURN VALUES
  The routine returns 0 if it is successful. Otherwise, it returns -1 and
  errno is set to reflect the cause of the error.
