[Cross posting to Cygwin list as this is a more general discussion IMO]

Boot time is neither magic nor pulled out of thin air.
Checking *my* system processes using wmic queries and elevated powershell
scripts, the boot time is at most a few seconds off from process start times
from other sources.
I understand that other systems may run processes where that is not the case.
Please explain why you think this is misleadingly not useful, or where or which
processes have unvailable start times that are not very close to boot time.
