Electronic Timer Maintenance

Yesterday my oldest customer called. They are a private school and the timer that rings their school bell had a problem. It is an Intermatic ET70115C and since the US moved the week that daylight savings changes, this timer can't automatically change at the right time any more. You can buy a new chip that does it, but they haven't spent the money on it.

Anyway, the office manager tried to manually change the time and ended up adding an additional ring on the bell. I removed this extra ring and we traded this service call for an ad in their school directory.

If they mess it up again, maybe they will let me either find a different timer (that a layman can actually configure), or at least replace the old chip.
