If you remember correctly, the autoexec.bat file had TIME & DATE
commands in it so that DOS would not ask you for the date and time when
you booted the system. And this was a carry over from CP/M's lack of a
need for a stable TOD.
Correction1: You were asked about date and time when you didn't have
autoexec.bat.
Correction2: The reason was *lack of timer*, not unstable one. First PCs
had no timer at all. No battery. Like ZX Spectrum or Atari 800, or
Amstrad CPC 6128, ...
Battery clock was add-on feature (a card) on PC XT and became standard
in PC AT.
BTW: the clock in PC was (*is*) inaccurate by design.
Of course the above and any rant on non-IBM platform does not justify,
why STP for time synchronisation is so expensive. It's only software,
and same software (in functions performed) on other platforms is free.
