Q: Will resetting parameter RAM (a.k.a.NVRAM) cause
a Macintosh computer to reset the Date & Time Preferences?
I use the keyboard sequence "command-option-p-r"
when I start a Macintosh.
A: No, the Date and Time functionality is contained
in the PMU, Power Management Unit hardware, which is located
on the motherboard. The keyboard sequence, command-option-p-r
resets NVRAM, non volatile random access memory. NVRAM contains
Open Firmware configuration variables and other non clock
data.
