Actually, the marked answer originally produced wrong results for milliseconds 1 - 99: Example 1 second, 27 milliseconds: DATEDIFF % 1000 will return 27; CONVERT will convert to '27' String concatenation will build '1' + ',' + '27' Result: '1. You can simply use DateDiff. DECLARE @NumberOfSeconds int SET @NumberOfSeconds = 3843 -- 1 hour, 4 minutes, 3 seconds SELECT @NumberOfSeconds AS 'seconds', CONVERT (varchar, DATEADD (second, @NumberOfSeconds, 0), 108) AS 'hh:mm:ss'. The datepart parameter identifies which date and time boundaries to compare. And the second query return milliseconds. A database function can be invoked with or without parameters, and it computes the result based on the parameter values. It can be used to do date math as well. g. For example, you can use: SELECT TIMESTAMPDIFF (SECOND, '2012-06-06 13:13:55', '2012-06-06 15:20:18') In your case, the third parameter of TIMSTAMPDIFF function would be the current login time ( NOW () ).
