[time-nuts] TEC party file format?

I'm planning on counting 60Hz line cycles with some embedded 
hardware, then dumping the count over RS-232 every minute or so to a 
linux box running ntp.  Any thoughts on what data to log?

Obviously, the 60 Hz cycle counter.

Timestamp when data was received at the serial port?  (It looks like 
my box has the high-res timers, so I can get it down into fractional 
seconds pretty easily).

Line voltage?

Some of the NTP status?

I'm thinking one line per sample, with commas as delimiters.  Sound good?
