Comment:

Something really strange is going on there. The log timestamps are complete weird. First it starts out with 3:40:57.076 - 3 hours and 40 mins since the application started - which is something I find rather hard to believe. Then it suddenly drops to 00:00:00.000 which I find very hard to explain, unless by chance we're hitting a very high number that happens to have the lower end as all zeros...

Anyway, both the VM and this log timestamp uses the same time source so at least there is some kind of consistency here. The time is jumping back and forth about 3:4 every so often.

I wonder if it could've been a compiler optimization issue that we've fixed since 1.4.0, that's currently my best guess. (It could also be a out-of-sync TSC issue, but I can't imagine how that could be.)
