Add date time picker to element.

array	$a_custom_config
string	$a_id2
array	$a_custom_config2

Returns

string

Whether the start of the week in the picker is Sunday or Monday should depend on the user calendar settings (#21666). Unfortunately this is not a direct config of the picker, but is inherent in the locale, so it needs to be shoehorned into there.

0 for Sunday, 1 for Monday
