This sounds like you're referring to leap seconds, where due to the Earth's rotation slowing down (as determined by the International Earth Rotation Service), an extra second is inserted every so often, typically in July; it's quite fun watching it on a GPS receiver (assuming that it even survives the event, as I've seen a few cheaper ones lose the plot). There is a serious proposal to phase out leap seconds (no URL handy right now), and I have no idea how that will affect time-based security. -- Dave Horsfall DTM (VK2KFU) "Bliss is a MacBook with a FreeBSD server." http://www.horsfall.org/spam.html (and check the home page whilst you're there)
