The start of the $GPZDA is specified to match the PPS output.  
Interesting that the others are one second slow.  Any missing sentences 
were not sent.

I was also listening to WWV at 5 MHz, but I missed the leap second by 
two seconds.  I haven't listened to WWV in a long time; instead of the 
normal ticking sound, each tick was tripled--sort of a ti-tick tock 
sound.  I know I wasn't hearing WWVH (no female voice announcements).  
Was I hearing some other time station or is that how WWV sounds now?
