I seem to have hallucinated that the built-in convert handler recognised the ISO date and dateTime formats (YYYY-MM-DD, YYYY-MM-DD hh:mm:ss+-hh.ss, etc) but I must have written my own conversion routines in a former life. But one would have to ask… Why doesn’t it? After all, the original ISO 8601 standard was adopted 1988! Neville Smythe
