I am in Atlanta until next Thursday. When I got to work today, I had calendar notifications going off on my phone, which were an hour off. I finally found the setting that fixed this on my iPhone. I honestly didn’t know if it was just a glitch, or what. But honestly, I don’t know why this option exists. Why would you not not want your calendar to match the time/time zone of your phone? Seems odd to me. Nevertheless, here is how to fix it.
→ Start by tapping the Settings icon
→ tap Mail, Contacts, Calendar
→ scroll all the way to the bottom of the page and tap “Time Zone Support”
→ Set to OFF
