You may need to change time zones in PennO365. For example, if you're traveling overseas and see a proposed meeting in the PennO365 Calendar, you can change the time zone to Eastern Time to see when the meeting will occur in Philadelphia. Then you can change back to your local time zone. You can change time zones in PennO365 whenever you wish.
If you've never set up a time zone in OWA, it will default to "(UTC) Monrovia, Reykjavik", which is Coordinated Universal Time (also known as Greenwich Mean Time).
If you're using the Outlook desktop client, consult Microsoft's instructions, "Add, remove, or change time zones - Outlook".
