Kanzaki-san,

Thanks very much for the test file. I checked it and found two cases of
errors being reported:

1. Local times without seconds.
2. Fractional seconds with more than three digits.

About the first case, that was a bug and the cause was an oversight that had
the effect of making the code require seconds on local times -- despite the
fact the spec says they're optional. I've now pushed a fix for that out to
the validator.

About the second case, that's not a bug, because the spec does actually
require the fractional parts of seconds to be one, two, or three digits:

  http://www.whatwg.org/specs/web-apps/current-work/multipage/common-microsyntaxes.html#valid-time-string

So the examples in that spec such as "14:54:39.92922" are actually not
valid datetime values, and so for that I've filed a spec bug:

  https://www.w3.org/Bugs/Public/show_bug.cgi?id=19732

Thanks again and if you find other problems in the validator behavior for
datetime checking, please do let me know.
