Yet the problem of an oscillator having a high drift rate after long-term
storage is not one that a development team is likely to be thinking about.
Nor is it a problem that can be easily examined, since it requires a bunch of
old units lying around the development lab. Old units don't exist when the
product is new, and even if they had traveled back in time to buy and age a few
units, after sufficient testing they would stop drifting and therefore be
useless for the test.
Nevertheless, 25 years later we expect the whiz-bang engineers at HP to have
thought of the problem and solved it.
