Hi all, I originally thought having the timezone in the header of the file would make things simpler, since it meant all the timestamp would be in the same timezone, rather than potentially different ones. But it seems that that might not be inline with how others use their org files.
org actually already has a keyword for a per entry timezone, https://orgmode.org/manual/iCalendar-Export.html The problem with it is that no other facility of org plugs into that, it only counts when exporting into other calendar systems, which I think is strange. If it is indeed better to be able to set timezone per entry, then I think supporting this properly in org would be best. Only having CST etc timezone abbreviations is indeed problematic, because it is ambiguous and kinda difficult to enter, also people don't necessarily communicate with the correct designation (maybe they mean EDT but used EST, but the time is unambiguously EDT). With repeat tasks I don't think it would be a problem for tasks that repeats daily or longer (since by definition they add to the day/month/year directly, not counting how many days there are in a month for example). For hourly repeating tasks it is indeed ambiguous, but I don't have an idea on what would be better. Maybe people that have those can chime in. Best, Shironeko
