Hello Vidhu,
Welcome to Microsoft Q&A!
Changing the time zone of a Service Principal is not a supported operation in Azure, as Service Principals do not have a configurable time zone setting.
If you could provide more details about your specific requirements or the scenario you're working on, we’d be happy to assist you with more accurate and tailored guidance. For now, please note that Azure services operate in Coordinated Universal Time (UTC) by default, regardless of their geographic location.
Feel free to share additional context so we can help further!
Thanks
Deepanshu
