Declare @dt0 datetime, @dt datetime, @LocalTimeOffset int=5.5*60*60, @epochdt bigint=1389595157, @AdjustedLocaldt bigint;
SET @AdjustedLocaldt = @epochdt + @LocalTimeOffset
SELECT @dt0=DATEADD(second,@epochdt, CAST('1970-01-01 00:00:00' AS datetime))
,@dt=DATEADD(second,@AdjustedLocaldt, CAST('1970-01-01 00:00:00' AS datetime))
; with mycte as (SELECT @epochdt as epochdt, @dt0 as gmtdt , @dt as localdt
, DATEADD(minute, DATEDIFF(minute,0,@dt),0) as StartOftheMinute
,DATEADD(hour, DATEDIFF(hour,0,@dt),0) as StartOftheHour
, DATEADD(day, DATEDIFF(day,0,@dt),0) as StartOftheday
, DATEADD(mm, DATEDIFF(mm,0,@dt),0) as StartOfThisMonth
, DATEADD(year, DATEDIFF(year,0,@dt),0) as StartOftheYear
, DATEADD(wk, DATEDIFF(wk,0,@dt),0) as StartOftheWeek)
select epochdt,
Left(datename(weekday,localdt),3) +' '+ CONVERT(varchar(26),localdt,109) as localdt
,Left(datename(weekday,gmtdt),3) +' '+ CONVERT(varchar(26),gmtdt,109) as gmtdt
