Hello Mark,

thanks for reaching out to us.

Amelia doesn't have any time zone settings, and it relies on WordPress' General settings. Here's how it works:

All times in the back-end of Amelia will be shown exactly how you save them, so (for example) if your employee works from 09:00 - 17:00, or if there's an appointment from 09:00 - 10:00, that's how you will see them in the back-end.

If you enable "Show booking slots in client time zone" in Amelia's General settings, though, that may not be what your customers see, depending on where they're located, and what your WordPress site has been configured.

I recommend taking a look at this article to get a better picture - Time Zones with Amelia

Please, let me know if you need help with anything else.
