[!INCLUDE sql-asdb-asdbmi-asa-pdw-fabricse-fabricdw-fabricsqldb]
Returns a datetime2 value that contains the date and time of the computer on which the instance of [!INCLUDEssNoVersion] 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.
For an overview of all [!INCLUDEtsql] date and time data types and functions, see Date and time data types and functions (Transact-SQL).

SYSUTCDATETIME ( )
datetime2
[!INCLUDEtsql] 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
[!INCLUDEssNoVersion] 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 [!INCLUDEssNoVersion] is running. The precision of this API is fixed at 100 nanoseconds. The accuracy can be determined by using the GetSystemTimeAdjustment() Windows API.
The following examples use the six [!INCLUDEssNoVersion] 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.
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()]; [!INCLUDEssResult]

The following example shows you how to convert date and time values to the date data type.
SELECT CONVERT (date, SYSDATETIME())
,CONVERT (date, SYSDATETIMEOFFSET())
,CONVERT (date, SYSUTCDATETIME())
,CONVERT (date, CURRENT_TIMESTAMP)
,CONVERT (date, GETDATE())
,CONVERT (date, GETUTCDATE()); [!INCLUDEssResult]

The following example shows you how to convert date and time values to the time* data type.
DECLARE @DATETIME DATETIME = GetDate();
DECLARE @TIME TIME
SELECT @TIME = CONVERT(time, @DATETIME)
SELECT @TIME AS 'Time', @DATETIME AS 'Date Time'[!INCLUDEssResult]
