Time zones in Azure SQL Database Managed Instance

Coordinated Universal Time (UTC) is the recommended time zone for the data tier of cloud solutions. Azure SQL Database Managed Instance also offers a choice of time zones to meet the needs of existing applications that store date and time values and call date and time functions with an implicit context of a specific time zone.

T-SQL functions like GETDATE() or CLR code observe the time zone set on the instance level. SQL Server Agent jobs also follow schedules according to the time zone of the instance.

Note

Managed Instance is the only deployment option of Azure SQL Database that supports time zone setting. Other deployment options always follow UTC. Use AT TIME ZONE in single and pooled SQL databases if you need to interpret date and time information in a non-UTC time zone.

Supported time zones

A set of supported time zones is inherited from the underlying operating system of the managed instance. It's regularly updated to get new time zone definitions and reflect changes to the existing ones.

Daylight saving time/time zone changes policy guarantees historical accuracy from 2010 forward.

A list with names of the supported time zones is exposed through the sys.time_zone_info system view.

Set a time zone

A time zone of a managed instance can be set during instance creation only. The default time zone is UTC.

Note

The time zone of an existing managed instance can't be changed.

Set the time zone through the Azure portal

When you enter parameters for a new instance, select a time zone from the list of supported time zones.

Setting a time zone during instance creation

Azure Resource Manager template

Specify the timezoneId property in your Resource Manager template to set the time zone during instance creation.

"properties": {
                "administratorLogin": "[parameters('user')]",
                "administratorLoginPassword": "[parameters('pwd')]",
                "subnetId": "[parameters('subnetId')]",
                "storageSizeInGB": 256,
                "vCores": 8,
                "licenseType": "LicenseIncluded",
                "hardwareFamily": "Gen5",
                "collation": "Serbian_Cyrillic_100_CS_AS",
                "timezoneId": "Central European Standard Time"
            },

A list of supported values for the timezoneId property is at the end of this article.

If not specified, the time zone is set to UTC.

Check the time zone of an instance

The CURRENT_TIMEZONE function returns a display name of the time zone of the instance.

Cross-feature considerations

Restore and import

You can restore a backup file or import data to a managed instance from an instance or a server with different time zone settings. Make sure to do so with caution. Analyze the application behavior and the results of the queries and reports, just like when you transfer data between two SQL Server instances with different time zone settings.

Point-in-time restore

When you perform a point-in-time restore, the time to restore to is interpreted as UTC time. This way any ambiguities due to daylight saving time and its potential changes are avoided.

Auto-failover groups

Using the same time zone across a primary and secondary instance in a failover group isn't enforced, but we strongly recommend it.

Warning

We strongly recommend that you use the same time zone for the primary and secondary instance in a failover group. Because of certain rare use cases keeping the same time zone across primary and secondary instances isn't enforced. It's important to understand that in the case of manual or automatic failover, the secondary instance will retain its original time zone.

Limitations

  • The time zone of the existing managed instance can't be changed.
  • External processes launched from the SQL Server Agent jobs don't observe the time zone of the instance.
