I work security with a large group of people. We rotate to different positions every 30 minutes so, therefore, I must constantly watch the time. I cannot keep count of the times during the day that I look at my digital watch, that has the seconds on it, and I see it turn from 59 seconds to 00 seconds; or I see it go from 00 seconds to 01. This has been going on for months. Also, within the past two weeks, I have begun seeing our digital clocks at home change from one minute to the next.
