There may be various reasons you want to turn the Alternate Timezone feature on or off, depending on your company's location and your customer base. Follow these simple steps to allow or prevent users from making appointments in timezones other than that of the business:

Step 1: Navigate to Settings > Company

Step 2: Click or un-click the "Disable Contact Timezone" check-box. When the box is checked, Contact Timezone is disabled, meaning all appointments will be in your company's selected timezone. When the box is un-checked, a customer can book an appointment in their own timezone.

Note: Once the "Disable Contact Timezone" box selected, all appointments will be made in the timezone set under Settings > Company > Time Zone. Additionally, the timezone dropdown won't be viewable in the calendar widget.
