Dealing with incomplete dates, the function "guesses" the rest of the date, which it should not do: {{#time:j|April 2013}} returns the same result as {{#time:j|1 April}}. Both are 1 but in case of April 2013 it is an assumption. Depending what users are doing with the result things could take a wrong turn on there wiki's. The desired result should be something that can not be a day, like 0 so users can "catch" it. As the behaviour might be dealt with in several wikis, I suggest to include a settings parameter, where users can swith the guessing on or off. So users who need the guessing can still activate it (or on the other hand users who need a correct handling of incomplete dates can deactivate it).
