AZ timezone not working

[Moderator note: Topic title de-capped. Please do not shout at us.]

I live in AZ and since daylight savings went into effect last week, my post are all off on the date that they actually have posted and so is the time. AZ doesn’t ever change time zone. I am still on PHX time in my settings but it is saying my date is actually 1 day behind the correct date. The time is also off. Please help!
