Dennis,

... unless you have a small computer which does not have its own RTC, but
just depends on an always-available connection to "thar intawebz" - which it
isn't.

Than I hope that the Pi's internal clock never runs fast. Otherwise the
first re-syncing with an ntp server would cause a problem.
Ofcourse, making the clock jump forward as a result of that re-syncing might
not be good for something-or-another either. :-p

Does an atmel mega32 (and family) also count ?

Yup, the famous "epoch".    But I would really like to see your calculation
to convert the year, month, day, hour, minute and second values into such a
float.   You know the joke about "and than you have two problems" ?   That
also seems to be true for home-made date/time functions.
