This is follow-up from email I sent to email@example.com Mike Copestake told me to continue support here.
WP is set to Winnipeg time (CDT)
On the site where appointments display it shows UTC
Now click on a time to register... It now shows CDT. This page is actually correct.
It also shows UTC in Admin for Working Hours.
Timezone should always be CDT, that is set in WP.
Please advise for fix. Thank you.
