Re: Cost effective time servers

I would submit that the proper use of a GPS receiver is for alignment
of the start of the second to a more precise value than can be
distributed across an asymmetric network like the Internet.  The
actual 'time label' for that second doesn't necessarily need to come
from GPS at all.  For security reasons, it's probably a good thing to
make sure you validate the data received from GPS in any case.
