Leap bugs are NOT known. Most people have no idea unixtime is not monotonically increasing. I had no idea myself until sunday, I had assumed we really go 59 -> 60 -> 00, but we go 59 -> 59 -> 00. So 59.1 can happen before or after 59.2. To me this is fundamentally and inherently broken. It's quite hard to find code which stores timestamp and then compares it in future to timestamp which assumes time can travel backwards. Most bugs are just things that should last 5s last 6s or 4s, but certainly the bugs exist and developers were not aware that they exist. -- ++ytti
