Could you tell me when will this be done? Second, this staying DST change is a bit confusing for me. Should it be that Russia will return to Russian Standard Time and will increase time zone offset by one ? But from the proposed change, the offset is not change. Am I missing something here?. Lastly, I have seen the term of UTC+2 and UTC+2+1. For UTC+2+1, is it referring to time zone offset plus 2 with DST forward by one? Your help is appreciated.

Does anyone have insight into the dates when standard timezones, based from Greenwich and at 15 degree intervals (as are still used in international waters) started coming into general acceptance or law? Am I correct to assume that the first place to use 'standard time' was Britain in 1847, but that the international acceptance of a 'world' timezone system based on GMT offsets only really started with Sir Andrew Fleming's proposals in 1879? Also, before that, when did 'mean time' as opposed to 'solar time' start coming into general acceptance? I read that it was when accurate mechanical clocks started becoming available in the early 1800s. Anyone have an approximate date for first adoption of mean time by a city?
I think I saw a comment in the database portion (Eurpoe file) that there was a standard zone as early as 1835 around Belgium / Netherlands. ----- Original Message ----- From: "David Patte" <dpatte@relativedata.com> To: <tz@lecserver.nci.nih.gov> Sent: Saturday, May 07, 2011 9:06 AM Subject: Standard Time Zones & Local Mean Time

These are complex questions, hinging on subjective interpretations of the terms involved, such as "general acceptance". The book "Greenwich Time and Longitude", by Derek Howse, has a lot of information about standard time in Great Britain. For example, he writes (pp. 114-15) that in 1858, a court decided that legal time "must be understood as the mean time at the place where" an event occurs, "and not Greenwich time, unless it be so expressed." Prior to that, there had been "nothing on the statute book to define what was the time for legal purposes" -- but at that date "98% of the public clocks in Great Britain were set to GMT." On August 2, 1880, it finally became law that "[w]henever any expression of time occurs in any Acts of Parliament, deed, or other legal instrument, the time referred shall, unless it is otherwise specifically stated, be held in the case of Great Britain to be Greenwich mean time, and in the case of Ireland, Dublin mean time." (Copyrighted material, quoted under fair use.) So perhaps that answers part of your inquiry. You may have to hit the books in a good library if you want more complete answers.

as of now, State Duma web site shows that current Bill 509727-5 has pass on first reading (on April 19, 2011) and amendments to the bill will be accepted within fifteen days ... (However there are lots of holidays in Russia between May 1 and today- May 9- Victory Day) State Duma will finalize the bill after amendments for approval on second reading. Alexander Krivenyshev http://www.worldtimezone.com
Russian State Duma passed the third reading of the bill 509727-5 "On the Calculation of Time" (in Russia) and adopted a law abolishing the transition to daylight saving time. Bill itself does not mentioned anything about daylight saving time, however Article 10 repealed the law «On regulation of calculating time on the territory of the Russian Federation" from October 23, 1991 № 1790-I, which defines introduction of Daylight Saving Time (Summer Time) in Russia. Original Bill "On the Calculation of Time" is on State Duma documents web site (in Russian): http://asozd2.duma.gov.ru/main.nsf/(SpravkaNew)?OpenAgent&RN=509727-5 or (in Russian) http://www.worldtimezone.net/dst_news/dst_news_russia31.html P.S. There is also no specific and details for each Time zones in Russia. Alexander Krivenyshev http://www.worldtimezone.com
Do we know what the next steps are on this? At what point can we proceed with an update to the database? Thanks, Deborah On May 20, 2011, at 11:56 AM, Alexander Krivenyshev wrote:

Deborah, there are no specific for each current time zones of Russia regards changes or move to new time zones. However it seems that Russia will keep current DST permanently and all current time zones could be changed in database (without DST). I am traveling right now to Russia.
