Timestamp Internet Headers for Office 365

[LyndonC]

I have noticed after moving to Office 365 email, the Internet headers time stamp is now GMT, for example, Fri, 13 Sep 2019 21:37:03 +0000. 

When I am still in onprem, the time stamp is in PST, for example, Tue, 20 Aug 2019 10:47:03 -0700. 

How do I change the time stamp back to PST for Office 365.

You cannot, that's controlled on the server and you simply don't have access to change it in O365.
