[time-nuts] GPS with PPS

Does anyone know if any of those all-in-one hockey puck GPS receivers
put out PPS on the serial cable? The type that has the antenna and GPS
together, with a serial cable hanging off of it. I'm thinking about
using one for a timing project. The more sensitive, the better, as it
will be used indoors.

While I'm on the subject of GPS units, a question comes to mind. I
know that WAAS enhances position accuracy. Does it do anything for
time? My first thought would be no, as that comes directly from the
standard GPS satellites.
