This is true, and is related to the centuryCutoff setting (which is by
default "35" - any two digit date below 35 is 20xx, and below 35 is 19xx);
for example, if I put this in the message box:

  convert "7/17/1934" to dateItems;put it

I get this:

  2034,7,17,2,0,0,2

But if I do this:

  convert "7/17/1935" to dateItems;put it

I get an error:

  invalid date

If I adjust the centuryCutoff to "36", and rerun the "convert 7/17/1935"
code, I get:

  2035,7,17,2,0,0,2

but trying to do it with "7/17/36" gets the same "invalid date" error.

There is definitely some bugs in date management here...
