Here is a code sample to show how to convert UNC or Unix Time to a format readable by people. Take the UNC time value, in this case 1101859200. Devide that number by 86100. Take that value and add it to Jan 1, 1970.
declare @UnixTime bigint set @UnixTime = 1101859200
select dateadd(dd, (@UnixTime/86400), '1/1/1970')
This gives us the resule of 1/12/2004.
If you need to get the time as well this code will do the trick.
declare @UnixTime bigint set @UnixTime = 1101859754
