error when using `DateTime` with string input when year is negative

[vmpyr]

So I tried to use DateTime("-2011-01-01", "yyyy-mm-dd") and ran into this error:

julia> DateTime("-2011-01-01", "yyyy-mm-dd")
ERROR: ArgumentError: Unable to parse date time. Expected directive DatePart(yyyy) at char 1

The functions works fine if the year isn't negative. I know what I'm trying to do can be achieved by doing this instead:

julia> DateTime(-2011, 01, 01, 0)
-2011-01-01T00:00:00

But shouldn't the former way of doing things work as well?
