Future time

I have by good authority that the "next generation" of PC Mother-boards
will not use quartz crystals to generate clocks. They will use ceramic
resonators such as the kind made by muRata (www.murata.com). These
devices are surface-mount "chips" to reduce cost, and provide only
2 percent accuracy as compared to 0.001 percent accuracy from typical
crystals presently used.

Since time-keeping is important, and inaccuracies are cumulative, we
will have to come up with software fixes, possibly using the CMOS timer
for periodic re-calibration.

Cheers,
Dick Johnson
