like when I do 

SELECT [Date]
  FROM [FRIIB].[dbo].[ArchiveAnalog]
  GROUP BY [Date]

how can I specify the group period ?

MS SQL 2008

2nd Edit

I'm trying 

SELECT MIN([Date]) AS RecT, AVG(Value)
  FROM [FRIIB].[dbo].[ArchiveAnalog]
  GROUP BY (DATEPART(MINUTE, [Date]) / 10)
  ORDER BY RecT

changed %10 to / 10. is it possible to make Date output without milliseconds ?

GROUP BY
DATEPART(YEAR, DT.[Date]),
DATEPART(MONTH, DT.[Date]),
DATEPART(DAY, DT.[Date]),
DATEPART(HOUR, DT.[Date]),
(DATEPART(MINUTE, DT.[Date]) / 10)
