Weird problems too
Got a very strange call from the school district superintendant that a local high school was having a problem with the clocks getting reset every night. Didn't rally excite me but turned into a real cloak and dagger search for the fault. After resetting the clocks first thing in the morning, checked out the main controller that tells all the clocks(240 of them) when to advance the minute hand. Couldn't find anything that would lead to this fault occurring and tried inducing a few things to try and duplicate the failure. No luck and the same fault occurred again that night. After resetting the clock I set up a power line monitor on the outgoing lines to see when and what was going on. The next morning the same fault and the monitor picked up all kinds of garbage on the line around 7PM, when the school was closed up. Getting really strange. I asked the principal for a key to try and be present when the fault occurred and arrived at 6PM that night to see what's going on. Around 730PM I started watching the clocks ticking off the minutes like it was the second hand. I took a quick tour of most of the class rooms and all the clocks were winding around like mad. I then found a janitor in one of the shops area running a buffer over the floor. I asked him to stop for a minute and the clocks stopped dead in their tracks. After scrounging around in their maintenence bin I found a set of brushes for the buffer motor and he went back to work and I went home. Strangest problem I've seen in the last decade.
