Barakta's realised that the reason she keeps being late for meetings is that her ork laptop has a clock that makes the one on our microwave look accurate. For some inexplicable[1] reason, Windows is configured to sync with "Local CMOS clock", rather than one of the myriad time servers on that internet they have now.
[1] I'm betting there are Domains involved.
That just sounds All Wrong, but I've seen similar.
If the machine is part of a Windows Domain, it will be automagically configured to use SNTP take it's time from one of the Domain Controllers, which in turn will be synced to a Proper Time Source.
In a Windows Domain, the clients and servers need to be tightly time-aligned for their authentication protocols to work. ( To avoid replay-attacks ).
So for this reason, the servers serve time, the clients accept it, and everything works.
How it all works when everyone is off-line and WFH, It's more complicated.
But I've seen similar: my work laptop at home is off-domain, and time drifts. I've not checked the settings. But I've not got the VPN up, so I'm not attempting to connect directly to Domain resources. I think if I connected to the Domain network by VPN or physical connection, it would sync.
Most of the stuff I connect to is cloud-based now, so the time thing doesn't come into it.
