It's "stratum", and denotes the authoritativeness of the time source.
Lower numbers are better. A reference clock is stratum zero. A machine
that is connected to a reference clock is a stratum one source. Machines
connected to it are stratum two, and so on. Kind of like RIP hops. :-)
Reference clocks are devices directly synchronized to a standard such as
GPS, radio signals from WWV, etc. If your home lab is on the Internet,
you can derive timing from a public NTP server. List here:

It's considered polite to use a stratum 2 server unless you intend
to synchronize a large network to it. Picking one that is geographically
and logically close to you is a good idea.
Alternatively, just pick a host or router as your master running free.
This won't give you accurate time but will allow you to play with NTP
and its nuances.
