DecodeFileTime
This method enables the generation of a PLC variable of the type FILETIME from a standardized ISO8601 time format (e.g. YYYY-MM-DDThh:mm:ss). FILETIME corresponds to the number of nanoseconds starting from the date 01.01.1601 – measured in 100 nanoseconds. If the conversion was successful the method returns TRUE, otherwise it returns FALSE.
