Modulo latencies and jitter from different machines to the log server. Millisecond precision can be harmed by this, easily. Especially by jitter and order of millisecond here isn't something non-existent in a long-distant networks. -- Eygene Ryabinkin, National Research Centre "Kurchatov Institute" Always code as if the guy who ends up maintaining your code will be a violent psychopath who knows where you live.
