Hi Andre,
Thanks for the advice. I'll consider it for the next version. I'm
going to change it anyway, because I want to hook directly into the
network time protocol and avoid using telnet.
Currently, I am only retrieving the time. I'm slowly getting familiar
with the protocol and will probably apply the necessary math at some
point.

Mark,
I've implemented a couple servers for tiny protocols and have looked a
little into SNTP some years ago. Are you aware of the latency issue
right and the math you need to do to compute the delay between the
server answering stuff and you actually receiving it. I've looked into
the RFC and some other docs and decided against implementing SNTP
readers, the math was kinda confusing.
As for the line:
read from socket theServer with message "rcvTime"
you might want to change that to some other command with some
termination clause, I can't recall the protocol of SNTP but use
something like read ... until or read for ## bytes and use a buffered
read operation. I've found that plain read calls can block till
eternity and should be avoided.
