Discussion on "@UTC" stated with this message by Christian:
https://lists.gnu.org/archive/html/emacs-orgmode/2023-02/msg00016.html
Theses were examples shown:
> Examples:
> 2022-11-12 12:00+02 # 12:00 UTC+2
> 2022-11-12 14:00+0230 # 14:00 UTC+2:30
> 2022-11-12 14:00-0230 # 14:00 UTC-2:30
> 2022-11-12 14:00Z # 14:00 UTC
Those examples are correct but there is comment "#" which was talking
about prefixes, only for understanding.
Examples without comments are:
> 2022-11-12 12:00+02
> 2022-11-12 14:00+0230
> 2022-11-12 14:00-0230
> 2022-11-12 14:00Z
As you can see there is "Z" as designation for UTC time. When there is
designation for UTC time, no prefix is mentined.
You may observe that UTC prefixes in those examples are mentioned with
positive or negative prefixes, but there is no designation for "UTC",
as that would become confusing.
Which is what I was speaking about.
Where you Ihor responded with this message:
https://lists.gnu.org/archive/html/emacs-orgmode/2023-02/msg00018.html
> [2022-11-12 14:00 @UTC+2]
> [2022-11-12 14:00 @UTC-2:30]
> are also fine within the proposed format.
I am not sure what did you intend to show, did you intend to tell
that:
- 2022-11-12 14:00 @UTC+2 means 2022-11-12 12:00 @UTC ?
In my understanding "@UTC" means "UTC time zone". From above first
examples it is very confusing to use "UTC" as designation plus
positive or negative prefix.
It is not common to represent it that way. As if there is any
designation for UTC, like "UTC" or "@UTC" or "Z", then there is no
prefix shown, or if any, there will be zero.
And I said, representing time that way by mixing word "UTC" with
prefix would be confusing, as that practically creates new type of
time representation that is not ordinarily used.
