Although there are likely some dark corners where bugs can be found, I
think you could probably add timezone data to org timestamps by changing
the default format strings. Org also uses an 'internal' 'time' value to
represent timestamps which are then converted to the required format
using these format strings.

What is possibly missing is an easy way to specify a time zone when
creating a timestamp. I suspect it will default to whatever the local
system tz is and I don't think there is any convenient way to change tz
values like there is for the other timestamp components.
