Sometimes the magic works, and sometimes it doesn't

We have these spiffy "atomic" clocks here at DeskSlave Central. The clocks aren't really atomic, actually, no plutonium to worry about, but they do have some sort of fancy satellite uplinks that connect them to the atomic clock in Colorado.* Or so they say. I really have no way of checking. It could just be some old cheapie quartz clock like I have in the kitchen of stately DeskSlave Manor, repackaged with an impressive-looking atomic logo and a hefty upcharge. In any event, some of the clocks here have adjusted themselves to Daylight Savings Time, but some have not. It has been more than 24 hours since the putative switch, yet the clock at the circulation desk is still unaware. I am told this several times a day by helpful patrons, so I just have to shrug and give them the "shortcomings of technology" spiel.


* Question for you: why does the Navy had an observatory in landlocked Colorado?
