Like that it gives the time every 5 seconds instead every 60 seconds like WWV.
But, I agree with Grant. The guy’s voice gets boring. Maybe he could impersonate Donald Duck just to break things up a bit.

This clock is good but the announcer is so monotone. I call in at all hours of the day to see if anyone else is announcing the time but it never fails, this guy announces the time 24⁄7. Overall the service is pretty good. Helps keep my Casio on time. I even used this to program the time on my microwave and my VCR. I’ll never be late recording the Andy Griffith show again!

Great for syncing your watch to be on the exact timeline as other aircraft. Being I. The navy, I decided to have the official time. I can never be late to anything if my watch is correct.

I’ve missed the days since you could dial P-​O-​P-​C-​O-​R-​N to get the exact time. I know that we now have the actual time available online–
and that is why we lost the popcorn phone number but I’ve always missed being able to call from anywhere and find out exactly what time it is. I recently found out about the US Naval Observatory Master Clock phone number.

It’s nice to know the time to the precise second (Damn, My watch is two seconds slow and I have to fix that right now)
Now everyone on Unilocal will know what my OCD is.
