Convert ymd to a standard string formatting policies.
This is standard code for handling date formatting with year-month-day based date information. This function uses the format_type to control whether the string will contain separator characters, and if so what the character will be. In addtion, it can format the month as either an integer or a string as controled by the formatting policy
