What is the sequence of time zones from Georgia to California?

Answer 1

If you take Interstate-20 west from Georgia to I-10 and I-10 to California, you pass three time changes on the way as follows:

If you're traveling between the 2nd Sunday of March and the 1st Sunday of November, you start in Eastern Daylight Saving Time or EDT (UTC-4)...

• On I-20 between GA Exit 5 & AL Exit 210, you turn your watch back one hour to UTC-5 (Central Daylight Saving Time or CDT).
• On I-10 between TX Exit 138 & TX Exit 133, you turn your watch back another hour to UTC-6 (Mountain Daylight Saving Time or MDT).
• Between NM Exit 3 & AZ Exit 390, you turn your watch back the third hour to UTC-7 (Mountain Standard Time or MST).
• Between AZ Exit 1 & CA Exit 243, you enter Pacific Daylight Saving Time (PDT), but there is no time change. There is no time difference between Mountain Standard Time and Pacific Daylight Saving Time.

If you're traveling between the 1st Sunday of November and the 2nd Sunday of March, you start in Eastern Standard Time or EST (UTC-5)...

• On I-20 between GA Exit 5 & AL Exit 210, you turn your watch back one hour to UTC-6 (Central Standard Time or CST).
• On I-10 between TX Exit 138 & TX Exit 133, you turn your watch back another hour to UTC-7 (Mountain Standard Time or MST).
• Between AZ Exit 1 & CA Exit 243, you turn your watch back the third hour to UTC-8 (Pacific Standard Time or PST).
