I simply want to be able to have meeting times set as UTC and let org tell me when it is depending on which time zone I am in (as I always update the timezone on my laptop when I change timezones). Getting caught up with what happens at the transition to daylight savings etc. is just a distraction, in my view. Being able to specify UTC timestamps and have them displayed in local time will be an incredible step forward for time related management in org. Does it solve everything? No. But the current situation is a mess for timezone related issues and this enhancement would be very welcome. Thank you, eric --=20 : Eric S Fraga, with org release_9.6-201-gb58fba in Emacs 30.0.50=
