I run TIME686 automatically every time I boot the machine.
Since I shut down at least every night, the clock is always
pretty close, within a few seconds seems close enough for
timestamps. The wife's windows machine gains 2.5+ seconds/day.
The OS/2 machine is better, <1 second/day.

I figure near-monotonic time is good enough for what I need.
And I really Like Norbert Dey's TIME868 program, even though
the last release was since Dec '96.

What is the significance of using startup.cmd as opposed to the startup
folder, aside from running earlier in the boot-up process?

Am I missing something I should be considering?
