It's probably not relevant, but we have seen time "run backwards" on multi-core systems using AMD processors. Such unusual events have the ability to play hob with any scheme that expects monotonically increasing time and can be surprisingly difficult to debug - some things do happen "once in a blue moon".

We've only seen this happen at micro-second time scales so I doubt very much it is a concern for your application, but it could be if the same technique were used to generate ids across threads.

True laziness is hard work
