The cns7648 format is based on the National Standards of the Republic of China CNS 7648 which is similar to the ISO 8601 standard. This is implemented using text rules with the hyphan '-' as a separator. This is the same as the minus character which means it is not possible to show negative years. Therefore proleptic dates are not available with this format.
