If it is a unix timestamp you need to add 1/1/1970 to get the date.
Then use CONVERT to format the date
- SELECT CONVERT(VARCHAR(DATEADD(SS,{1217508668},'19700101'),109))
I think this will convert your timestamp to mm/dd/yyyy hh:mm pm format.
But this is a string format.
To get to SQL Server format CAST AS DATETIME is needed
Not sure about Crystal Reports
