RTIME(3)		 BSD Library Functions Manual		      RTIME(3)

NAME
     rtime — get remote time

LIBRARY
     Standard C Library (libc, -lc)

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
     rtime() 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 rtime() function returns the value 0 if successful; otherwise the
     value -1 is returned and the global variable errno is set to indicate the
     error.
