Re: Interesting problem: eval-after-load and local variables

[Michael Heerdegen]

Hello,

I think you need to use `setq-default' instead of `setq' - see the
manual for details.  So, that should work:

(eval-after-load "time-stamp"
  ;; format of the string inserted by `M-x time-stamp'
  '(setq-default time-stamp-format "%:y-%02m-%02d %3a %02H:%02M %u"))
