Article is POV as it favours the US states as more important than the Canadian provinces --Nick Dillinger 08:34, 27 January 2006 (UTC)

I'm living in the MST part of Canada and I'm not sure why it seems to favour the US. Canada is listed first, followed by Mexico and then the US. If I remember right there is part of the NWT (Cantung) that is on Pacific (Yukon) time and part of BC that is on Mountain. CambridgeBayWeather (Talk) 09:12, 27 January 2006 (UTC)

A bigger concern is that "standard time" is only synchronized with UTC-7 during regular (non-daylight saving) days. During daylight saving, most of this region springs forward by one hour and goes with UTC-6. I hope we can get this right before April 2nd. --Uncle Ed 18:47, 23 March 2006 (UTC)

this really should be on the time zone talk but Mountain Standard Time (MST) is always -7. From the first sunday in April to the last sunday in October most places listed here would be on Mountain Daylight Time (MDT) or rarely called Central Standard Time. CambridgeBayWeather (Talk) 20:49, 23 March 2006 (UTC)

Yes, of course you are exactly right. MST is always in effect, 365 days a year in Arizona (except the non-Hopi parts of the Navajo reservation). During Daylight Saving Time - which by the way is 57% of the year! - most of the Mountain Time Zone goes on MDT.

The question is whether time zones are places and standard & DST are times, as I figure. Or do the names of the zones change twice a year? Authorities vary, and I daresay no one really cares as long as the clocks are set correctly :-) --Uncle Ed 22:02, 23 March 2006 (UTC)

It's more traditional in the US to use _DT under daylight savings time but _ST is also commonly used. It's not the wiki's job to tell folks their doing it wrong anyway. Jon 19:05, 26 June 2006 (UTC)

This article is about the time zone with daylight change in North America. For the static time zone, see UTC−07.Esmito (talk) 19:05, 27 April 2010 (UTC)

uncited material cut

"Jackpot, Nevada observes Mountain Time unofficially because of close economic ties with southern Idaho. Although officially on Mountain Time, Fort Pierre, South Dakota keeps Central Time because of its proximity to Pierre." Anything that would be in violation of offical standards needs cited.

Major metropolitan areas

Why not include Rapid City, SD? -Amit, 03/01/07

MT & DST observance / Canada

Fort St. John, British Columbia claims that the region observes Mountain Time, but does not participate in DST. Can we verify if that's true for all parts of British Columbia in MT? If so, it should be mentioned here - it is for Arizona, et al. samwaltz 23:10, 24 August 2007 (UTC)

Name page?

Mountain Time Zone or Mountain Time Zone north America or Mountain Time Zone (north America) ? 222.252.255.116 01:41, 8 November 2007 (UTC)

Well if there are no other Mountain Time Zones then it wouldn't need the "North America" disambiguation. CambridgeBayWeather (Talk) 23:10, 9 November 2007 (UTC)

Clock

I've seen user pages where there's a clock showing the time in that users time zone, would it be appropriate to put such a clock on the page showing the current mountain time? TastyCakes (talk) 16:36, 9 August 2008 (UTC)

Better Image Needed

it is not immediately clear where MST lies from the image. Trying to find it is difficult due to the small size of the text in the picture. I suggest the replacement image mark MST in red and leave the other zones all the same color. Whatever style is used should be standard across the time zone wikis —Preceding unsigned comment added by 72.21.196.64 (talk) 14:23, 23 January 2009 (UTC)

I agree. The present map is too small to be useful. Needed is a map of US/Canada, so readers can quickly see what states and provinces are included. 173.75.43.71 (talk) 17:26, 12 January 2010 (UTC)

Malheur County

It appears from maps in phone books that part but not all of Malheur County, Oregon, is in the Mountain Time Zone, the remainder being in Pacific. It would be helpful if this could be clarified and noted on the county's article. --Haruo (talk) 03:51, 6 September 2008 (UTC)

WikiProject Canada?

It seems strange that this page is part of WikiProject Canada but not part of WikiProject United States or WikiProject Mexico. Should we consider removing the WikiProject Canada tag? Guy Macon (talk) 22:23, 21 March 2011 (UTC)

Arizona on MST, not PDT.

I do not believe the following statement concerning Arizona is correct, "... because of this, it is said to be Pacific Daylight Time and NOT Mountain Standard."

According to timeanddate.com, "... Arizona is not on PDT because this term is a daylight saving time/summer time zone." http://www.timeanddate.com/time/us/arizona-no-dst.html

According to NIST.gov, "Most of Arizona is MST year-round" http://www.nist.gov/pml/div688/localtime.cfm — Preceding unsigned comment added by 32.97.110.52 (talk) 17:58, 6 December 2011 (UTC)

If a state in the Mountain Time Zone can be said to be on Pacific Daylight time, one could claim that the Pacific Time Zone states observing Daylight Saving Time are on Mountain Standard Time and NOT on Pacific Daylight time. Clearly this is nonsensical. Arizona doesn't become part of the Pacific Time Zone during the summer and then revert back in the winter. So I changed the paragraph. The claim was unsourced anyway.

--Trappist the monk (talk) 19:56, 6 December 2011 (UTC)

This point especially matters when we stop observing clock change. I agree, With the exceptions of Navajo Nation observing UTC-6 while Denver is currently in MDT, AZ is operating in UTC-7 just as the Pacific and that's why it's the same local time in Phoenix as it is in Seattle right now. In Oct 2022 Sinaloa "pulled an Arizona" and also permanently enacted MTS but is also falsely labeling itself as "mountanous" instead of "Pacific" as it observes UTC-7 and will do so permanently. So we have created 2 states AZ and Sinaloa, co-existing and currently operating on MTS labeled as "mountanous" but physically observing UTC-7 "Pacific" time. PDT = MST = MPST = UTC-7 = OR, WA CA BC Baja Peninsula Mazatlan

MDT = UTC-6 = Mexico City, Durango, most of Mexico (different time zone so there is an hour difference)

If AZ and the coastal regions of Mexico don't change to a Pacific suffix and remain considered mountainous, international planning and even locals may not notice the change or conversion of MST vs MDT which currently coincide simultaneously like never before.

This matters because the Sunshine Act just passed approval from the Senate and states we all remain on daylight, no more clock changes and no more rogue states being required to stop on standard time due to 1966 law. Therefore, MTS must be converted namewise to be in alignment with Pacific. Otherwise, the ancient predicted time of Mazatlan's upcoming total solar eclipse will continue to be falsely advertised in UTC-6 time and not as locally observed UTC-7 with totality peaking at 11:07am not noon like the rest of Mexico. 173.241.161.229 (talk) 02:50, 12 May 2023 (UTC)

Rocky Mountain Time?

In a version of "Inherit the Wind", the lawyer for the teacher asks the lawyer for the state if the time that God created the Earth, 9:00 a.m., was "Eastern? Or Rocky Mountain?" Are we to understand that at an earlier time, the time zone name was Rocky Mountain? Is there any historical record for such an official name, and if so, when was it officially shortened simply to "Mountain"? GBC (talk) 07:28, 1 January 2014 (UTC)

It's been nine years. Has nobody looked into this? GBC (talk) 04:30, 7 January 2023 (UTC)

Current time is consistently incorrect

The current time box gave a time from yesterday. Refreshing it gave a time that was roughly 75 minutes old. I think this box should be removed unless it can be made consistently correct without any user interaction. No sane clock has a "show correct time" button that doesn't even work. 192.12.184.6 (talk) 17:35, 5 March 2018 (UTC)

DST in infobox

The infobox says "DST is observed in all of this time zone." Why isn't it "DST is observed except in Sonora, most of Arizona, and a few places in British Columbia."? If it's because this article is only about the places with daylight saving time (#MT & DST observance / Canada), then DST is observed everywhere by definition, and the largest city in such a zone wouldn't be Phoenix.

Editor BrandonXLF broke {{Infobox time zone}} with this edit.

Map with states

The map would be MUCH more useful if it had states and provinces shown 107.77.206.23 (talk) 15:34, 24 September 2023 (UTC)
