My RAZR lies
I’m convinced that my Motorola RAZR cellphone does not tell time accurately.
The phone has a little external LCD panel that displays the time and other pertinent information so that I don’t have to flip the phone open to check on things. Normally, this panel is not backlit in order to conserve energy, but there’s an easily accessible button on the edge of the phone that lights up the screen. When I hit the button to check the time on my phone, about forty or fifty percent of the time the digital clock ticks over to the next minute.
That’s very odd; I’m not looking at the screen for more than two seconds (max). That means, I’d expect to see the minute change about once every thirty times, assuming the times at which I check the time are uniformly randomly distributed within the sixty second interval between minute digit changes. One out of thirty is not even four percent; there’s an order of magnitude difference between the expected and observed values. I must have checked the time on with the phone more than five hundred times by now, so this is definitely statistically significant. This discrepancy leads me to the following hypothesis.
My RAZR is programmed to change the minute digit on the display when I click the button if its internal clock is within a twenty or thirty second window around the actual time at which the seconds should roll over back to zero.
If true, it’d have to have been a deliberate design decision. Perhaps people remember the time better after reading a digital clock if they see the digits change and Motorola is just helping me out? I haven’t yet thought of a different explanation.
