How to know there was a power outage and for how long?
Between the analog clock and the digital clocks that reset to 12:00 and start counting when powered back on, you can figure out the time of the failure and duration. If you have all battery powered clocks with quartz oscillators or atomic (really, radio set clocks referenced to atomic clocks at NIST) clocks then you may not know.
Can a power failure cause a digital clock to stop working?
In the latter case, the clock functionality is probably toast. In the former case, you might be able to find a secret setup EEPROM variable triggered by something like holding keys down as the unit is powered up or something like that.
What happens to a clock when the power goes out?
This clock keeps you protected even during power outages because the battery power picks up when the electricity goes out. Keep in mind that the batteries on these clocks do eventually run out, so make sure you have fresh batteries in your home.
What to do when your alarm clock stops working?
When you need your alarm clock to ensure you make it to your destination on time, you want to do everything possible to make sure your alarm clock keeps running. Try an atomic clock that is designed to keep the time even through power failures or an electric clock with backup battery power.

What causes a weight driven clock to stop working?
If it bumps anything, even slightly, then it loses some momentum and the clock will eventually stop. If these things do not fix the clock then it would be safe to assume there is a general lack of power in the time train. It is time to give the Weight Driven Clocks clock a good cleaning and check it over for excessive wear.
