This is both an operating system and application problem. http://infiniteundo.com/post/25326999628/falsehoods-programmers-believe-abou... http://infiniteundo.com/post/25509354022/more-falsehoods-programmers-believe... This is similar to the jiffycounter wrapping, since this doesn't happen that often, it's not commonly tested for. Good way is to start the jiffy counter so it wraps after 10 minutes of uptime. That way you'll run into any bugs quickly. Either we should abolish the leap second or we should make leap second adjustments (back and forth) on a monthly basis to exercise the code. This is a hard sell though... -- Mikael Abrahamsson email: swmike@swm.pp.se
