Converts the value in <Date> to data type DateTime ONLY if all characters in <Date> correspond to a valid DateTime mask (format). The date portion is the same as the <Date> value and the time portion is set to 00:00:00 in the timezone specified by <String>, which is the timeZoneOffset. The timeZoneOffset must take the form of a valid timezone offset such as ‘-08:00’, ‘+03:30’, ‘01:45’
