Comment 2 for bug 824638

Andrew, I'm not sure whether it'll just work, you'll have to try it and see if you need to do a bit of messing around with strptime like on the view access page, which uses get_string('strftimedatetimeshort'). Might not be a big deal with the date of birth because you never need to compare times, it's just making sure the input format is converted to the db format accurately.
