After doing a little research, "DOS TIME" was based on GMT only, thus the need
to include
the Time Variable "SET TZ= EST?EDT" (or whatever your offset is/was) !!!

Yes it was !!!

That's my guess also, I'm waiting to see how things play out !!! Obversely I'll
be doubly
checking CT's time vs GMT for the next few weeks !!!

EST4EDT !!!

speaking) !!!

Hence the next problem to be addressed. Things don't seem to work wright with
