OK, this is what I propose now for America/Creston ... Zone America/Creston -7:46:04 - LMT 1884 -8:00 - PST 1918 Jun 2 -7:00 - MST As best I can tell, from reading the article that inspired the need for the new zone http://www.ilovecreston.com/?p=articles&t=spec&ar=260 this reflects (close enough anyway I think) what has actually happened. LMT until 1884, PST until June 1918, then MST ever since. All we're missing is the time of day that the switch from PST to MST actually occurred, but my guess would be, that nothing we put there would actually match reality, so I think we can just leave it like it is (and if anyone actually has a timestamp from the early hours of the morning Sunday June 2, 1918, from Creston) then we'll simply ask them to note that we're not sure what precise time it represents. Does that look OK to everyone? lre
