Last year I replaced the battery in a smoke detector as it was alerting on low battery. Since it is good to change them annually, I put the date in my BlackBerry calendar to remind me in a year. Two days ago, that same detector alerted on low battery. I changed the battery and forgot about it. Yesterday I got a popup reminder to change that battery. I though it was interesting the detector alert happened so close to one year so I told the story to the members of the house. The one non-BlackBerry user made a comment about the BB being wrong. I reminded the person this is a leap year. Ergo, there is one extra day this year (after February 29th). So the BB was right, the calendar was wrong.

Obviously the battery life can't be that precisely measured so, I assume the smoke detector has a second counter and when it hits 31557600 seconds (365.25 days) it triggers the battery change alert. I wonder if it runs QNX as the OS?

Oh and by the way, there was a leap second added this year on June 30th.

Around here they recommend changing them every 6 months (whenever the time changes) but glad to hear you got it changed!
