converting unix dates

Hi,
Does anyone know of a quick an easy way of convertiing unix date serials eg
12815 to March 31 2005).
Any pointers appreciated
Thanks

I would have expected
select dateadd(ss, <UNIX_timestamp>, '19700101')
to have worked which implies 12815 either wrong or not a unix timestamp!!

the number of days since some date. For example:
DECLARE @.t INTEGER
SET @.t = 12815
SELECT DATEADD(DAY,@.t,'19691231')
Result:
2005-01-31 00:00:00.000
(1 row(s) affected)
or:
SELECT DATEADD(DAY,@.t,'19700228')
Result:
2005-03-31 00:00:00.000
(1 row(s) affected)
DATEADD is probably the function you need in any case.

Jens, John & David, that solved my problem. Turns out I got the number wrong
should've been 12873
Thanks

SELECT DATEADD(d, 12815, '01 Jan 1970')
