您必须重新格式化字符串以及转换为正确的时间。在这种情况下，我需要祖鲁时间。

Declare @Date datetime;
Declare @DateString varchar(50);
set @Date = GETDATE(); 
declare @ZuluTime datetime;

Declare @DateFrom varchar (50);
Declare @DateTo varchar (50);
set @ZuluTime = DATEADD(second, DATEDIFF(second, GETDATE(), GETUTCDATE()), @Date);
set @DateString =  FORMAT(@ZuluTime, 'yyyy-MM-ddThh:mm:ssZ', 'en-US' )  
select @DateString;

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。

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

如果你的本地日期时间是东部标准时间，你想从UTC转换为UTC，那么在Azure SQL和SQL Server 2016及以上版本中，你可以这样做:

SELECT YourUtcColumn AT TIME ZONE 'UTC' AT TIME ZONE 'Eastern Standard Time' AS
       LocalTime
FROM   YourTable

时区名称的完整列表可以在以下地址找到:

SELECT * FROM sys.time_zone_info 

是的，时区的命名很糟糕——即使是东部标准时间，也考虑到了夏令时。

对于任何仍然试图解决这个问题的人，这里有一个在SQL Server 2017中工作的概念证明

 declare
    @StartDate date = '2020-01-01'

;with cte_utc as
(
    select 
         1 as i
        ,CONVERT(datetime, @StartDate) AS UTC
        ,datepart(weekday, CONVERT(datetime, @StartDate)) as Weekday
        ,datepart(month, CONVERT(datetime, @StartDate)) as [Month]
        ,datepart(YEAR, CONVERT(datetime, @StartDate)) as [Year]
        
    union all

    Select
         i + 1
        ,dateadd(d, 1, utc)
        ,datepart(weekday, CONVERT(datetime, dateadd(d, 1, utc))) as Weekday
        ,datepart(month, CONVERT(datetime, dateadd(d, 1, utc))) as [Month]
        ,datepart(YEAR, CONVERT(datetime, dateadd(d, 1, utc))) as [Year]
    from    
        cte_utc
    where
        (i + 1) < 32767

), cte_utc_dates as 
(
    select 
        *,
        DENSE_RANK()OVER(PARTITION BY [Year], [Month], [Weekday] ORDER BY Utc) WeekDayIndex
    from
        cte_utc

), cte_hours as (
    select 0 as [Hour]
    union all
    select [Hour] + 1 from cte_hours where [Hour] < 23
)

select
    d.*
    , DATEADD(hour, h.Hour, d.UTC) AS UtcTime
    ,CONVERT(datetime, DATEADD(hour, h.Hour, d.UTC) AT TIME ZONE 'UTC' AT TIME ZONE 'Central Standard Time') CST
    ,CONVERT(datetime, DATEADD(hour, h.Hour, d.UTC) AT TIME ZONE 'UTC' AT TIME ZONE 'Eastern Standard Time') EST
from
    cte_utc_dates d, cte_hours h
where
    ([Month] = 3 and [Weekday] = 1 and WeekDayIndex = 2 )-- dst start
    or 
    ([Month] = 11 and [Weekday] = 1 and WeekDayIndex = 1 )-- dst end
order by
    utc
OPTION (MAXRECURSION 32767)

GO

我有代码执行UTC到本地和本地到UTC时间，允许使用这样的代码进行转换

DECLARE @usersTimezone VARCHAR(32)='Europe/London'
DECLARE @utcDT DATETIME=GetUTCDate()
DECLARE @userDT DATETIME=[dbo].[funcUTCtoLocal](@utcDT, @usersTimezone)

and

DECLARE @usersTimezone VARCHAR(32)='Europe/London'
DECLARE @userDT DATETIME=GetDate()
DECLARE @utcDT DATETIME=[dbo].[funcLocaltoUTC](@userDT, @usersTimezone)

这些函数可以支持NodaTime提供的IANA/TZDB中的全部或一部分时区-请参阅https://nodatime.org/TimeZones上的完整列表

请注意，我的用例意味着我只需要一个“当前”窗口，允许在大约+/- 5年的范围内转换时间。这意味着，如果您需要很宽的时间段，我使用的方法可能不适合您，因为它在给定日期范围内为每个时区间隔生成代码的方式不同。

这将生成如下示例所示的SQL函数代码
