As we sent an inquiry regarding the switching time to the regular summer time matter earlier, could you please provide us some recommendations on below. The Government of Mongolia is planning to switch to the regular summer time from 22-26 March, 2024. Currently, the discussions are made within the Government as well as at the Parliament. We expect that final decision will be made in the October. Therefore, is it possible to arrange the switching process in the next 5 months? Is there any extraordinary cases like us or not? Or shall we make our changes in the September 2024? Thank you for your kind consideration in advance and hope to hear from you soon.
Dear Ms.Ariuntuul, Major systems and software organizations and projects have posted that it can take many months to produce properly tested official updates to time zone and summer time data, so more advance notice in official publications is better. Late changes have resulted in business, economic, and travel disruption costing many millions for many governments and businesses, as well as reputational harm from effects, and resultant future impacts. It would probably be fair to say that, as governments have to provide adequate advance notice, to international organizations such as IATA, of dates and times of changes to time zones and variations such as summer time, also informing this list at the same time should be adequate notice for changes, although for this list, the longer in advance the notice the better. This list also likes to be able to refer (users) to web links for government documents published on official sites (e.g. ...gov.mn) offering the (auto-translatable) digital texts of the relevant decrees, laws, orders, ordinances, regulations, etc. as modified and enacted into law. For example, the last major US change on 2007-03-11 was signed into law on 2005-08-08, passed by House and Senate in the previous month, the bill debated for months before that, and discussed for months before submission as a bill.
