My PST server time is still off

My friend is PDT and sees the server one hour ahead. I’m in AZ, and I still show it an hour earlier, even though we’re on the same time.

It’s 5am now for both PDT and MST.
PDT sees the server time as 5am.
MST (NOT MDT…MST…AZ) sees the time as 4am, which…is what it showed before when it ‘was’ 4am PST and 5am MST.
