No, you cannot add multiple timezones for your business operation hours. You are allowed to setup only one specific time zone for your Call Me Back configuration. Your customers will see time slots as per their device's time zone. * For example, suppose you have set up business operation hours as 10:00 am to 02:00 pm in the India Standard Time (GMT+5:30) time zone in your Call Me Back configuration. Now, suppose the customer you are calling is in Gulf Standard Time(GMT+4:00). Then they will see time slots like 08:30-09:00 am, 09:00-09:30 am, and so on. --- # Agent Instructions This documentation is published with GitBook.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter: ``` GET https://docs.truecaller.com/truecaller-for-business/features/call-me-back/can-i-add-multiple-timezones-for-my-business-operation-hours.md?ask=&goal= ``` `ask` is the immediate question: it should be specific, self-contained, and written in natural language. `goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal. The response will contain a direct answer to the question and relevant excerpts and sources from the documentation. Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
