rtime - get remote time

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

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

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\s0, however, the routine will instead use TCP and block until a reply is received from the time server.

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