A very nice problem description, illustrating what the code should accept
but doesn't.

You had me scratch my head by giving a reverse patch.

I think neither regexp is quite correct, assuming that SVN timestamp is
supposed to always have decimal point after seconds, with optional
fractional part, followed by Z (presumably to mean Zulu).

-                                           (\d\d)\:(\d\d)\:(\d\d).\d+Z$/x) or
+                                           (\d\d)\:(\d\d)\:(\d\d)\.\d*Z$/x) or

The decimal point should get quoted.
