Precise Time Setting ?

[catbird]

It seems as though many people here comment about the timekeeping precision of their watches, i.e., a few seconds fast or slow every so often. I would like to check mine, but have no idea what to use as a standard.

My question is:
Is there an online source that they are using to check the EXACT time? If not, what do people use to reliably check timekeeping?

Thanks.

OOPS!
I probably should have put this topic in the GDF (sorry).

Here is what I use, catbird.

Excellent... Thanks!

I have a Casio Waveceptor that syncs with WWV (http://tf.nist.gov/stations/wwv.html) for the sole purpose of setting my other watches.

I either use my wall clock that syncs via a radio signal, or this link:

I have Casio and a Citizen "radio controlled" watches which I use. Both recieve the signal regularly.
