Unfortunately, some of us have to deal with things like billing, transaction timing to validate what a client's logs might have on their systems, and so on.

My take on this is that second timing is close enough for this. And that all my internal systems need agree on the time. So if I'm off by 200ms or some blather from the rest of the world, I'm not overly concerned. I am concerned, however, if a random internal system is not synced to my own ntp servers.

This doesn't mean I don't keep our servers synced, just that being off by some manner of ms doesn't bother me inordinately. And when it comes to timing of events, yes, auto-increment IDs or some such are easier to deal with.
