Updates on Iranian Time Zone (IRDT)
Hi. Recently the Iranian parliament has decided to remove daylight saving from the Iranian time zone, eliminating the one-hour shift in the summer time. Hence, it is always going to be UTC+3:30. *This is not their final decision yet* and there is a final confirmation to be made, but I just wanted to inform you about the update to prepare possible modifications. I'm a software engineer and if we have the update on *tzdata* package as soon as possible, the software companies can adjust themselves accordingly. Please read these official news: https://www.isna.ir/news/1400122419045/ https://www.yjc.news/00Xw0k Regards, Ali Tofighi

Thanks for the heads-up. Please let us know if and when the Iranian government's decision becomes final. This news comes too late to make the deadline for TZDB 2022a, but if Iran changes its rules we'll need to release 2022b soon.
What are the chances they will be convinced to delay the decision taking place until next year? While the tzdb maintainer(s) can work hard to implement a change (less than six days before the next transition), the process of many organizations pushing that change out through multiple layers of operating systems, application software, and embedded systems (like smartphones and networking equipment) is much longer, and this will likely cause a lot of trouble. The tzdb environment has recommended such changes be made at least a *year* before they are to take effect. On Wed, Mar 16, 2022 at 11:21 AM Mohammad Ali Tofighi via tz <tz@iana.org> wrote:

The chances are high. Majlis (parliament) ratification should be further rectified by "Guardian Council" to become actual law and take effect. Guardian Council has 10 days to approve or reject it. If they approve it with delay (which is very probable), it will be enforceable from next year.

If my (Google-assisted) translation is right, I'm reading in the second-to-last paragraph something like: "If, for any reason, the implementation of this plan by the 1st of Farvardin, 1401 [2022-03-21] does not occur, the plan will be implemented from the 31st of Shahrīvar of the next year." Due to poor translation quality, it's not immediately clear to me whether that means "next year", as in the Persian year which is about to start in a few days (1401), or *the* next year after the one already mentioned (i.e., 1402). Depending on the meaning, permanent +0330 could take effect from 31 Shahrīvar 1401 (2022-09-22) or from 31 Shahrīvar 1402 (2023-09-22) if it's unable to come into force this week. Could you clarify your understanding from the original Persian as to the most correct interpretation of the delay provision here? -- Tim Parenti
Sorry for the confusion. Iranian year starts at March equinox (i.e. 1st Farvardin or 20th March). Daylight saving used to start at midnight 1st Farvadin. Till September equinox (i.e. 30th Shahrivar which is usually 22nd September). For six months.

Hi. Some updates on the Iran DST cancellation plans for next Iranian year: Official IR News Agency announcement: irna.ir/xjJ3TT Iran Parliament (Majles) official announcement : shorturl.at/fhtIR Highlights: DST will be cancelled for the next Iranian year 1402 (i.e 2023-March-21) and forthcoming years. Backgrounds: Iranian Parliament (Majles) had rectified a law to cancel DST for the current Iranian year 1401 (starting 2022-3-21) just one week before the new Iranian year. The government subsequently objected that such a rapid change of plans in a short period would be hard to implement and would harm financial, banking, telecommunication and other sectors. Due to this objection, the Iranian Guardian Council had returned the mentioned ratification to Majles to resolve this ambiguity. This was reviewed today in Majles with presence of Guardian Council representative. It is finally decided that this law should take effect from next year to allow the government to update their infrastructure. Best regards, Ali On 12/26/1400 AP 12:57 AM, Ali Mirjamali wrote:

The "short" in short links refers to their expected lifetime since they have twice as many chances to fail. Putting them in the comments in the file is practically meaningless. Redirects under target's control like the news site above are less problematic, but the other one, the one using generic shortener service, is *already* broken. -k
My apologies. Here is the complete link: https://www.parliran.ir/majles/fa/Content/articles/%DA%AF%D8%A7%D9%85-%D9%85... The reason I used a generic URL shortener was because of many UTF characters in the URL and lack of a native URL shortener on their website. On 2/21/1401 AP 5:04 AM, Kacper Gutowski via tz wrote:

Yes, that is indeed a bit long for a text file. I hope the other (shorter) link is enough for this.

Hi everyone. A couple of minutes ago they announced that the new rules *will not take effect* this March. However, the decision is on its way to become final in the coming weeks. They just said that it will not happen in the coming shift. Its reason wasn't about the IT industry at all. The Guardian Council has yet to decide on it and the government should implement it within 15 days of their approval, which causes them to miss the deadline! Please read it on the news as well: https://www.yjc.news/00XweA Kind regards, Ali Tofighi On Wed, Mar 16, 2022 at 4:23 PM Ali Mirjamali <alimirjamali@riseup.net> wrote:
