We should skip the regex matching if it does not exist

Currently, it is mandatory to specify a pattern if using
SIMPLE_DATE_FORMAT. However, in order to reduce schema complexity, we can allow users to not specify the patterns and use standard ISO time format to parse the date time.The ISO parser also supports optional. So users can simply use
yyyy,yyyy-MM,yyyy-MM-ddand so on.
