One topic that I rarely see on preparation sites, is the topic of keeping time without power. Most of the world uses their cell phone instead of a wrist watch. I used to wear a watch when I was doing x-rays, but switching to the MRI modality has me using the wall clock, and computer as my time pieces.
I know a few wall clocks use an AA battery that lasts for a really long time, but it doesn't have an alarm. Also, when the battery loses power, how are you going to reset the time?
What would you use in an EMP event or very long term power outage?
