…or at least they do at home.
I come into the office to work, and presume that the clocks on our phone system display would also be correct.
I don’t pro-actively make that presumption (as I would have tested this presumption) – I just assumed the time was correct.
Net result – I think the morning is going very fast, and I go for lunch an hour earlier than usual. I now have a much longer afternoon ahead of me.
At least my clocks at home mostly auto-correct themselves.
