Hi cryb, Obviously we do our best to ensure system time is accurate on all our machines. However, it's simply impossible to keep a large number of machines sufficiently well in sync that you can rely on montonicity (that values will only increase with time) across the service based solely on a wall-clock. If your app needs strictly increasing time for its operation, wall clock time alone will not provide that.
