We've had some problems like this before, and I think the date-parsing
code could probably be further improvement to do less silly things
when it sees unexpected input. That having been said, if you pass a
14-digit value to a date format that expects 8 digits, there's not
really any reasonable way for the computer to decide what you meant.
I gather that you'd like 20101216120525 to mean 2010-12-16 (and just
ignore 120525) but it could also be interpreted to mean
2010121612-05-25, which is admittedly an awfully long time from now
but it doesn't seem any less logical than randomly throwing away part
of the input string.
