Bingo!  My first attempt called it 'Date', which I ard realised was
pretty stupid.  My second try was "When", which is not listed anywhere
in their language reference, but still reserved - they have a
"whenever" which might explain it.  Double quotes or a totally
different name fix it.

For the record, DateTime objects work fine in all positions, and can
go down to 0.01 second resolution in a Sybase TIMESTAMP field.  In a
DATE field they get truncated to the nearest day, as expected.

The test output is handy, too - though I won't bombard M-A with all
300k now it works.

Thanks very much, everyone!
