is a date

[Roger Eller]

That's what I suspected.  So to build a slightly better trap, I am doing
this:

if tDate is a date and length(tDate) > 5 and tDate contains "/" then
   put "true"
   else
   put "false"
end if

I am sure there is probably a standard way to catch all possible date
formats (excluding "the seconds"), but this works for most.
