Similarities and Differences Between GETDATE and SYSDATETIME Date Functions

Prior to SQL Server 2008, there were only three functions that return the current system date and time of the computer on which the instance of SQL Server is running, namely CURRENT_TIMESTAMP, GETDATE and GETUTCDATE.  Beginning with SQLS erver 2008, three other date functions were introduced namely SYSDATETIME, SYSDATETIMEOFFSET and SYSUTCDATETIME.

The following article shows the similarities between the GETDATE() date function and the SYSDATETIME() date function.


  • Returns the current date and time of the computer on which the instance of SQL Server is running.
  • The time zone offset is not included on both functions.
