Bug #9951: DateTime.strftime and Time.strftime differ in how they treat "%L"

~~~ruby
DateTime.new(2014,1,2,3,4,5.678).strftime("%L")
# => "678"
Time.new(2014,1,2,3,4,5.678).strftime("%L")
# => "677"
~~~

I think these should both produce "678", but at the very least they should produce the same number so users don't have to special case one or the other. I realize there is floating point math under the hood here, but that's an implementation detail I don't think users should care about in this case.
