The diff-link shows an edit I did on wikipedia.de, which was done at 09:40, 9. Mai 2008 (see history), but the time stamp in the signature -- ~~~~ was replaced by a totally other date and time 23:55, 8. Mai 2008 (CEST).
That's danged odd...
a) I did a quick check just now of server clocks -- all Apache boxes are currently consistent.
b) If the page was saved by a server with a bad clock, it should have come up with the *same* wrong time for both the save and the signature.
One remote possibility is that it was saved on a server with a bad clock (set to PST, plus a few minutes off from correct) which corrected its clock *between* the signature replacement and the page save.
However logs don't appear to show any machines being replaced in service today, which would be the most likely trigger of such a scenario.
I'm going to consider this a freak occurrence and mark it WORKSFORME. But if you see it crop up again, do give a shout.
