SYSUTCDATETIME (Transact-SQL)
Applies to: SQL Server Azure SQL Database Azure SQL Managed Instance Azure Synapse Analytics Analytics Platform System (PDW)
Returns a datetime2 value that contains the date and time of the computer on which the instance of SQL Server is running. The date and time is returned as UTC time (Coordinated Universal Time). The fractional second precision specification has a range from 1 to 7 digits. The default precision is 7 digits.
Note
SYSDATETIME and SYSUTCDATETIME have more fractional seconds precision than GETDATE and GETUTCDATE. SYSDATETIMEOFFSET includes the system time zone offset. SYSDATETIME, SYSUTCDATETIME, and SYSDATETIMEOFFSET can be assigned to a variable of any one of the date and time types.

Transact-SQL syntax conventions
Syntax
SYSUTCDATETIME ( )
Return Type
datetime2
Remarks
Transact-SQL statements can refer to SYSUTCDATETIME anywhere they can refer to a datetime2 expression.
SYSUTCDATETIME is a nondeterministic function. Views and expressions that reference this function in a column cannot be indexed.
Note
SQL Server obtains the date and time values by using the GetSystemTimeAsFileTime() Windows API. The accuracy depends on the computer hardware and version of Windows on which the instance of SQL Server is running. The precision of this API is fixed at 100 nanoseconds. The accuracy can be determined by using the GetSystemTimeAdjustment() Windows API.
Examples
The following examples use the six SQL Server system functions that return current date and time to return the date, time, or both. The values are returned in series; therefore, their fractional seconds might be different.
A. Showing the formats that are returned by the date and time functions
The following example shows the different formats that are returned by the date and time functions.
SELECT SYSDATETIME() AS [SYSDATETIME()]
,SYSDATETIMEOFFSET() AS [SYSDATETIMEOFFSET()]
,SYSUTCDATETIME() AS [SYSUTCDATETIME()]
,CURRENT_TIMESTAMP AS [CURRENT_TIMESTAMP]
,GETDATE() AS [GETDATE()]
,GETUTCDATE() AS [GETUTCDATE()];
Here is the result set.
SYSDATETIME() 2007-04-30 13:10:02.0474381
SYSDATETIMEOFFSET()2007-04-30 13:10:02.0474381 -07:00
SYSUTCDATETIME() 2007-04-30 20:10:02.0474381
CURRENT_TIMESTAMP 2007-04-30 13:10:02.047
GETDATE() 2007-04-30 13:10:02.047
GETUTCDATE() 2007-04-30 20:10:02.047
B. Converting date and time to date
The following example shows you how to convert date and time values to date
.
SELECT CONVERT (date, SYSDATETIME())
,CONVERT (date, SYSDATETIMEOFFSET())
,CONVERT (date, SYSUTCDATETIME())
,CONVERT (date, CURRENT_TIMESTAMP)
,CONVERT (date, GETDATE())
,CONVERT (date, GETUTCDATE());
Here is the result set.
2007-04-30
2007-04-30
2007-04-30
2007-04-30
2007-04-30
2007-04-30
C. Converting date and time values to time
The following example shows you how to convert date and time values to time
.
DECLARE @DATETIME DATETIME = GetDate();
DECLARE @TIME TIME
SELECT @TIME = CONVERT(time, @DATETIME)
SELECT @TIME AS 'Time', @DATETIME AS 'Date Time'
Here is the result set.
Time Date Time
13:49:33.6330000 2009-04-22 13:49:33.633
