How about my patch? Notice that format-time-string is invoked with ZONE set to t so that TIME is always taken as UTC. Examples -------- ;;; locale en_US.UTF-8 ;; local time zone (Japan in this demo) (format-time-string "%A %T %z" 259200) => "Sunday 09:00:00 +0900" ;; force UTC (format-time-string "%A %T %z" 259200 t) => "Sunday 00:00:00 +0000" ;; locale de_BE.UTF-8 ;; local time zone (format-time-string "%A %T %z" 259200) => "Sonntag 09:00:00 +0900" ;; force UTC (format-time-string "%A %T %z" 259200 t) => "Sonntag 00:00:00 +0000"
