Time zones in Azure SQL Managed Instance
Applies to: Azure SQL Managed Instance
Coordinated Universal Time (UTC) is the recommended time zone for the data tier of newly developed cloud solutions, as it eliminates ambiguity. Azure SQL 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
Azure SQL Database does not support time zone settings; it always follows UTC. Use AT TIME ZONE in SQL Database if you need to interpret date and time information in a non-UTC time zone.
Important
When migrating your existing solutions to Azure SQL Managed Instance, consider carefully the timezone ramifications and as a rule of thumb match your original timezone settings unless you are reimplementing the relevant application logic.
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.
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.
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. As a workaround, create a new managed instance with the proper time zone and then either perform a manual backup and restore, or what we recommend, perform a cross-instance point-in-time restore.
- External processes launched from the SQL Server Agent jobs don't observe the time zone of the instance.
