How to prevent users from making appointments in timezones other than the business's timezone:


If you have a client whose business is near a timezone border (or maybe the business is in a popular tourist town that receives customers from other time zones) you may want to prevent people from being able to book appointments in their own timezones. 

You can do this in a location-level account by going to Settings, selecting the Company tab, then scroll down an activating the "Disable Contact Timezone" check-box. 

With the "Disable Contact Timezone" box selected, users will no longer see the timezone dropdown selector in the calendar widget, and all appointments will be made in whatever timezone is set in Settings > Company > Time Zone field.
