I do use magit, but I'm not good with it.  In particular, I wanted to
walk thru my changes with EDiff, but, when ediff brought up the buffers,
the buffers were in org-mode and everything was folded and I didn't see
how to tell ediff to not fold so I could see the diffs.

Change log:
================
Doc change to explain timestamps better

doc/org-guide.org (Dates and Times): purpose of timestamp + examples
doc/org-manual.org (Dates and Times): purpose of timestamp + examples
