So suppose I want to change the format from H@ M' S" to H:M.S, how
would I go about doing that? I tried (setq calc-hms-format "%s:%s.%s")
and (defcalcvar) in the same manner, but it just wouldn't work.
Looking in the source code, not being the best of Lisp hackers, it
seems that org-mode doesn't honor the variable.
