In some cases, the VARDATE formatting feature will accept DateTime data that doesn't explicitly match the FORMATIN string supplied. These cases are rare, but have been implemented to extend the usability of the VARDATE formatting feature.
When the two-digit month, day, hour, second, or minute formatting characters are supplied in the FORMATIN string and the matching value in the underlying data is a single digit, a zero will be prepended to the single-digit values before the data is converted to the format specified in the FORMATOUT string. When the full day name formatting characters are supplied in the FORMATIN string and the matching value in the underlying data is the abbreviated day name, the abbreviated day name will be accepted. Similarly, when the abbreviated day name formatting characters are supplied in the FORMATIN string and the matching value in the underlying data is the full day name, the full day name will be accepted.
