What is not "standard" about that date format?

Well, what you have is one of the standard date formats (20/120). I guess what you need is to pick which one you actually want... this might help you out:

SET DATEFORMAT MDY;

DECLARE @date DATETIME;

SET @date = '2011-03-01 13:10:29.817';

;WITH cte (Style) AS

(

SELECT 1 UNION ALL SELECT 2 UNION ALL SELECT 3 UNION ALL SELECT 4 UNION ALL

SELECT 5 UNION ALL SELECT 6 UNION ALL SELECT 7 UNION ALL SELECT 8 UNION ALL

SELECT 9 UNION ALL SELECT 10 UNION ALL SELECT 11 UNION ALL SELECT 12 UNION ALL

SELECT 13 UNION ALL SELECT 14 UNION ALL SELECT 20 UNION ALL SELECT 21 UNION ALL

SELECT 100 UNION ALL SELECT 101 UNION ALL SELECT 102 UNION ALL SELECT 103 UNION ALL

SELECT 104 UNION ALL SELECT 105 UNION ALL SELECT 106 UNION ALL SELECT 107 UNION ALL

SELECT 108 UNION ALL SELECT 109 UNION ALL SELECT 110 UNION ALL SELECT 111 UNION ALL

SELECT 112 UNION ALL SELECT 113 UNION ALL SELECT 114 UNION ALL SELECT 120 UNION ALL

SELECT 121 UNION ALL SELECT 126 UNION ALL SELECT 127 UNION ALL SELECT 130 UNION ALL

SELECT 131 UNION ALL SELECT 0

)

SELECT Style, DateOutput = CONVERT(VARCHAR(30), @date, Style)

FROM cte

ORDER BY Style;

the storage format isn't really important. The display is what is important. Display formatting is separate from how the data is stored.

AFAIK, you will have to convert this hours to characters or numbers and then do a CASE to determine if it's > 12. If so, subtract 12 and display that. You'll have to rebuild the string then to show the time.

I tried different formats on that site, but it does not work.

Care to elaborate on that at all?

Did your server just say "No."?

I tried a dozen or so of the formats, and none of them will convert 13:10 (in a datetime) to 1:10.

The only solutions I've seen were to convert to char, get the hours, do a CASE, and then rebuild a string.

Again, that is for display. What you see in SSMS or what is stored is irrelevant.

What about something along these lines?

SET DATEFORMAT MDY ;

DECLARE @date DATETIME ;

SET @date = '2011-03-01 13:10:29.817' ;

SELECT CONVERT(VARCHAR(30), @date, 101) +

RIGHT(CONVERT(VARCHAR(30), @date, 0), 7) AS [civilian_date]

If you provide an example of what you mean by "standard format" we can better assist.
