How to edit time details

What’s the correct procedure for editing the time details of a project?

Let’s say, for example I have a project start time of 8:15pm. But I want the start time to be 9:15pm. If I go into the details and manually change the 8:15pm time to 9:15pm, it jumps ahead 3 hours and sets it 12:15am.

What am I doing wrong?

Can you check that your timezone is set in /settings/localization

Looks like that fixed it. Thanks!
