During fall semester, you may have noticed several classrooms had stopped, slow, or otherwise malfunctioning clocks. You may have also noticed that the resolution wasn't always, er, timely. That's because the classroom clocks are synched and require more than a simple battery change to fix. After the actual power source is replaced, the clock requires re-synching to a satellite source. Completing this work requires an FM electrician, not a custodian, and some FM districts are short on electrician staffing, so the process may be delayed. Complicating the process is that some room users thought they could replace the battery themselves, but because the re-synching process did not occur, the clocks did not work correctly. The good news is that after the power replacement and re-synching is completed, the clock will keep time (and autocorrect) for approximately three years.
