[tz] Time Zone Iran

[Patrick.Stergonschegg at orf.at]

Hello,


I just noticed that the Windows time zone for "UTC +03:30 Tehran" is probably being computed incorrectly.


It seems that DST +1 is being added, although Iranian Government announced that they will not switch to DST anymore, beginning in 2023.


Official IR News Agency announcement: http://irna.ir/xjJ3TT

Current Time: https://time.ir


I assume that Microsoft imports IANA time zone data: http://bit.ly/3ZmGzTE


In the file tzdata2023b\asia on line 1625 it says:

3:30 Iran +0330/+0430


I assume the line should be changed and a new line should be added, e.g.:

3:30 Iran +0330/+0430 2022

3:30 - +0330

I am looking forward to any feedback.


Thanks a lot,
Patrick
