SQL Server UTC Date Functions

Ran across some SQL statements that were using the expression SYSUTCDATETIME() which is a statement I have not used and wanted to know the difference between this and my common go to statement of GETUTCDATE()

Test

select GETUTCDATE(), SYSUTCDATETIME()

Output

(No column name)	(No column name)
2019-06-17 16:52:18.693	2019-06-17 16:52:18.6947071

Looks the same to me

More detailed Test

Time to use the SQL_VARIANT_PROPERTY() function to obtain more details

select SQL_VARIANT_PROPERTY(GETUTCDATE(), 'BaseType') as DataType,SQL_VARIANT_PROPERTY(GETUTCDATE(), 'Precision') as PrecisionDetail,SQL_VARIANT_PROPERTY(GETUTCDATE(), 'Scale') as Scale
select SQL_VARIANT_PROPERTY(SYSUTCDATETIME(), 'BaseType') as DataType,SQL_VARIANT_PROPERTY(SYSUTCDATETIME(), 'Precision') as PrecisionDetail,SQL_VARIANT_PROPERTY(SYSUTCDATETIME(), 'Scale') as Scale

Output

DataType	PrecisionDetail	Scale
datetime	23	3

DataType	PrecisionDetail	Scale
datetime2	27	7

Turns out the more accurate variant is the SYSUTCDATETIME(), therefore going forward I need to use this when dealing with SQL Date times unless otherwise informed not to use that format
