This is very helpful.  It gives me HH:mm.  Is it possible to extract
HH.xx (hours and decimals) directly?

As far as I can find in the calc manual, I am told to set the
variable, but I have not been able to find out what is the format of
the variable?

For now I set GMT-10 by "s T', like this:
"GMT-10".

If I were to try to set ChST, the time zone more generally used on my
Island, would I have to edit also "calc-forms.el?  And what would I
need to enter?  There is no ChDT.

Your replies have been of inestimable help.  Thank you,
