A method for synchronising a computer's internal clock (and system time) with an external source, such as a computer with a more accurate clock.
Machines that are synchronised with an atomic clock or [GPS] are stratum 1. Machines that synchronise to these machines are stratum 2, and so on.

Clear generously provides a stratum 1 NTP server for public use:

However, you really shouldn't synchronise to a stratum one server for your small network - if everyone did that then the the server would probably need too much bandwidth. Please read http://list.waikato.ac.nz/pipermail/nznog/2001-October/003705.html. The difference in accuracy between syncing to a stratum 1 server and a lower stratum server is negligible!

consumer products, which eventually ended up using hundreds of Mbits/second of the university's bandwidth, even after they were forced to shut down the server.
