Good thing we are getting rid of standard time after this winter.I can't believe I have to spell this out to you...I thought only Hawks were this dense. SURPRISE!! MST = PDT... They are the same EXACT time. The rest of the mountain TZ will NOT align with AZ until they 'fall back' from MDT to MST.
Arizona's clock time today matches the rest of the Pacific TZ right now in PDT. In November, the clock time in AZ will not change and then it will match the rest of the Mountain TZ which will be back in MST.
If you look at the rest of the country, thier clock times for each TZ is always 1 hr apart going East to West, and they remain that way because they all 'Spring ahead' and 'Fall back' together. This means that relative to the actual clock time in the rest of the US, AZ changes which TZ it aligns with.
