Year 0 is a bit of an odd beast, see https://en.wikipedia.org/wiki/0_%28year%29 The parsing seems to go wrong in different cases: * 0 with precision year gives 0 * 0 with precision decade or larger gives +00000000000-01-01T00:00:00Z * 1+ with precision year works * 1-4 with precision decade gives +00000000004-01-01T00:00:00Z * 1-49 with precision century gives +00000000049-01-01T00:00:00Z * 1-499 with precision millenium gives +00000000499-01-01T00:00:00Z * etc See https://www.wikidata.org/wiki/Q5959 for an example. It's impossible to add the birth date now without causing a parse error on Wikipedia.
https://github.com/wmde/DataValuesJavascript/pull/49 is related to this (and several other report) but not an actual fix for the issue reported. To be honest I don't understand the issue. You are talking about "parsing errors" but the examples you gave just parse fine without an error. Unfortunately you don't explain what you expect.

On connected wiki's it gives parsing errors, I already got a angry Russian user on my talk page. If you access the property you get junk like "+00000000005-01-01T00:00:00Z".
See also https://bugzilla.wikimedia.org/show_bug.cgi?id=67604 Might be the same topic.
And here is the bug to the conceptional issue that leads (among others) to the concrete problem described above. https://bugzilla.wikimedia.org/show_bug.cgi?id=71289
(In reply to Maarten Dammers from comment #2) > On connected wiki's it gives parsing errors [...] junk like > "+00000000005-01-01T00:00:00Z". Again, what "parsing error"? Can you please give an example URL or steps to reproduce or the expected output or copy and paste the error message? An ISO date is neither "junk" nor a parsing error. The fact that you see an ISO date is the result of the fallback in the formatter as described in bug 67604. I would love to tackle this but based on that few information I barely can.
