Use telnet to obtain the time of day at several remote host sites. Are the times accurate relative to each other?

What will be an ideal response?

Look up the time service in /etc/services to find the port (you should find port 13). You can telnet
to port 13 on various hosts by specifying 13 as the second argument to telnet (the first argument is
the remote hostname to which to connect). Unless you happen to connect to sites that all update
their time from an accurate time server or WWV clock, you will probably find that they do not all
agree precisely.
