date and time sync failed

Same here. It is astonishing I could not manually set the time to fix this. Had a laptop I had not booted for a time, and just wanted to setup a little work area for my kid. Would not sync the time so it was basically a brick. My pin would also not work to get past the gatekeeper for the sync operation. Why would I need a pin to set the time? Couldn't I use my password? I gave up and literally threw the laptop away. That is the level of frustration I have with these sorts of issues. Such a waste of my time, and I put the blame squarely on microsoft.
