最简单的答案并不总是在底部，但这一次是，并且可以在上面的评论中看到。 使用您自己的“AT TIME ZONE”来捕获列/数据字段的TzOffset，而不是当前的SYSDATETIME。 在下面的数据中，2个查询，一个关于feb数据(DST是关闭的，在阿姆斯特丹的冬天)+1差异 第二次查询阿姆斯特丹4月份的数据，所以+2小时的差异。

    select top 2 month(receiveTimeUTC) as MonthInWinterOrSpring
   ,  receiveTimeUTC
   ,  CONVERT(datetime,  SWITCHOFFSET(CONVERT(datetimeoffset,  receiveTimeUTC),  DATENAME(TzOffset, SYSDATETIMEOFFSET()))) as LocalTimeWrongNoDST
   ,  CONVERT(datetime,  SWITCHOFFSET(CONVERT(datetimeoffset,  receiveTimeUTC),  DATENAME(TzOffset, receiveTimeUTC  AT TIME ZONE 'Central European Standard Time' ))) as LocalTimeWithDST
       from sensordetails order by id

    select top 2 month(receiveTimeUTC) as MonthInWinterOrSpring, receiveTimeUTC
,  CONVERT(datetime,  SWITCHOFFSET(CONVERT(datetimeoffset,  receiveTimeUTC),  DATENAME(TzOffset, SYSDATETIMEOFFSET()))) as LocalTimeWrongNoDST
,  CONVERT(datetime,  SWITCHOFFSET(CONVERT(datetimeoffset,  receiveTimeUTC),  DATENAME(TzOffset, receiveTimeUTC  AT TIME ZONE 'Central European Standard Time' ))) as LocalTimeWithDST
       from sensordetails order by id desc

结果:

所以这是一个T-SQL (SQL Server Answer)，不需要函数的storedproc。

下面是一个将夏令时考虑在内的更简单的例子

CREATE FUNCTION [dbo].[UtcToLocal] 
(
    @p_utcDatetime DATETIME 
)
RETURNS DATETIME
AS
BEGIN
    RETURN DATEADD(MINUTE, DATEDIFF(MINUTE, GETUTCDATE(), @p_utcDatetime), GETDATE())
END

罗恩的回答有一个错误。它使用当地时间凌晨2:00，其中需要UTC等效值。我没有足够的声望分数来评论Ron的回答，所以更正版本如下:

-- =============================================
-- Author:      Ron Smith
-- Create date: 2013-10-23
-- Description: Converts UTC to DST
--              based on passed Standard offset
-- =============================================
CREATE FUNCTION [dbo].[fn_UTC_to_DST]
(
    @UTC datetime,
    @StandardOffset int
)
RETURNS datetime
AS
BEGIN

declare 
    @DST datetime,
    @SSM datetime, -- Second Sunday in March
    @FSN datetime  -- First Sunday in November
-- get DST Range
set @SSM = datename(year,@UTC) + '0314' 
set @SSM = dateadd(hour,2 - @StandardOffset,dateadd(day,datepart(dw,@SSM)*-1+1,@SSM))
set @FSN = datename(year,@UTC) + '1107'
set @FSN = dateadd(second,-1,dateadd(hour,2 - (@StandardOffset + 1),dateadd(day,datepart(dw,@FSN)*-1+1,@FSN)))

-- add an hour to @StandardOffset if @UTC is in DST range
if @UTC between @SSM and @FSN
    set @StandardOffset = @StandardOffset + 1

-- convert to DST
set @DST = dateadd(hour,@StandardOffset,@UTC)

-- return converted datetime
return @DST

END

对甲骨文来说最好的方法:

硬编码的datetime:

SELECT TO_CHAR(CAST((FROM_TZ(CAST(TO_DATE('2018-10-27 21:00', 'YYYY-MM-DD HH24:MI') AS TIMESTAMP), 'UTC') AT  TIME ZONE 'EET') AS DATE), 'YYYY-MM-DD HH24:MI') UTC_TO_EET FROM DUAL

结果: 2018-10-28 00:00

列名和表名:

SELECT TO_CHAR(CAST((FROM_TZ(CAST(COLUMN_NAME AS TIMESTAMP), 'UTC') AT  TIME ZONE 'EET') AS DATE), 'YYYY-MM-DD HH24:MI') UTC_TO_EET FROM TABLE_NAME

使用新的SQL Server 2016机会:

CREATE FUNCTION ToLocalTime(@dtUtc datetime, @timezoneId nvarchar(256))
RETURNS datetime
AS BEGIN

return @dtUtc AT TIME ZONE 'UTC' AT TIME ZONE @timezoneId

/* -- second way, faster

return SWITCHOFFSET(@dtUtc , DATENAME(tz, @dtUtc AT TIME ZONE @timezoneId))

*/

/* -- third way

declare @dtLocal datetimeoffset
set @dtLocal = @dtUtc AT TIME ZONE @timezoneId
return dateadd(minute, DATEPART (TZoffset, @dtLocal), @dtUtc)

*/

END
GO

但clr程序的工作速度快5倍:'-(

请注意，一个时区的偏移量可以更改为冬季时间或夏季时间。例如

select cast('2017-02-08 09:00:00.000' as datetime) AT TIME ZONE 'Eastern Standard Time'
select cast('2017-08-08 09:00:00.000' as datetime) AT TIME ZONE 'Eastern Standard Time'

结果:

2017-02-08 09:00:00.000 -05:00
2017-08-08 09:00:00.000 -04:00

你不能只是添加常数偏移量。

这样就可以获得与夏令时同步的服务器时间

declare @dt datetime
set @dt = getutcdate() -- GMT equivalent

sysdatetimeoffset会考虑夏令时

select [InputTime] = @dt
       , [LocalTime2] = dateadd(mi, datediff(mi, sysdatetimeoffset(),getdate()), @dt)
