[time-nuts] quartz drift rates, linear or log

[Tom Miller]

Just out of curiosity, what is the age of each of these Tbolts? (i.e. date 
codes?)

Thanks

There were postings recently about OCXO ageing, or drift rates.

I've been testing a batch of TBolts for a couple of months and it provides 
an interesting set of data from which to make visual answers to recent 
questions. Here are three plots.
