…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.
*snarls*

At least my clocks at home mostly auto-correct themselves.
