GET_REAL_TIME was using the wrong offset and wasn't setting out_count.
May need to add time zone offset which could be different between host and guest.
get-time and set-time can be tested in Open Firmware.
SET_REAL_TIME is used by the Date/Time Control Panel when you change the date.
It is unknown what method Mac OS uses to get the time at boot. Mac OS 8.6 does not use GET_REAL_TIME during boot, so the time is left as 12:00 AM Jan 1, 1904.
Result of running IWYU (https://include-what-you-use.org/) and
applying most of the suggestions about unncessary includes and
forward declarations.
Was motivated by observing that <thread> was being included in
ppcopcodes.cpp even though it was unused (found while researching
the use of threads), but seems generally good to help with build
times and correctness.
