If @InputSecs < 60 and @InputSecs<>0
Begin
SET @HHMMSS = '0:01:00'
End
Else
Begin

SET @HHMMSS = ISNULL(CAST(@InputSecs/3600 AS nVarChar(MAX)) + ':' + RIGHT('0' + CAST(ROUND(CAST((@InputSecs % 3600.0) / 60 AS float),0) AS nVarChar(MAX)),2) + ':' + RIGHT('0' + CAST(ROUND(CAST((@InputSecs % 60.0) AS float),0) AS nVarChar(MAX)),2) ,'0:00:00')

End

Return @HHMMSS
End
