For instance, 10th March at 02:00 UTC (02:00 am) is taken as the same on 09th March at 09:00 pm EST (US). Dates must be considered properly while converting a time to or from UTC. During summers, add two hours i-e 18:00 UTC +2= 20:00 CEST. In order to convert 18:00 UTC into the local time of your region, add 1 hour to it. If you want to schedule any meetings or call anyone in a different time zone, you can use time converter to calculate time in their region. It can be used for conversion of current time and date or any future dates. Using time convertor, you can compare the time of your region to different time zones around the world. Was there a Day light saving time in the present year?.What day and month is it in the other time zone?.The hours and minutes currently passing by.The specific day and month in the other time zone.Apart from this, time convertor also assists you in the following calculations: When you are supposed to line up meetings or making a call with anyone residing in a different time zone, the time converter will help you to calculate the time in accordance with that part of the world. Moreover, it can also facilitate you to converter any dates, be they current, past or future.

This is also covered in the timezone tag wiki, in the section on Windows time zones.Time converter enables you to undergo a comparison of your particular area with other time zones across the globe. Do not try change it to "GMT Daylight Time" - that identifier doesn't exist. It is inclusive of both Greenwich Mean Time and British Summer Time, with the appropriate transitions between them. (Don't use switchoffset for this.)Īlso, the Windows time zone identifier for London is always "GMT Standard Time". The output of any of these is a datetimeoffset, which you can cast or convert to a datetime or datetime2 exactly as you showed in your original question. The first call to AT TIME ZONE asserts the value is in UTC, giving a datetimeoffset to the second call, which converts it to London time.
If inputdate is provided as a datetimeoffset value, then AT TIME ZONE clause converts it into the target time zone using time zone conversion rules.Ĭonsider that if your data actually comes from a datetime field somewhere, you might need to use both parts of the functionality, like this: SELECT mydatetimefield AT TIME ZONE 'UTC' AT TIME ZONE 'GMT Standard Time' This invokes the conversion functionality of AT TIME ZONE, which in the docs states: SELECT SYSDATETIMEOFFSET() AT TIME ZONE 'GMT Standard Time' The easiest way to handle this is to just fetch the UTC time as a datetimeoffset to begin with. So, even though you retrieved the UTC time, you erroneously asserted that the value was in London time (which is UTC+1 for daylight saving time at this date).
If inputdate is provided without offset information, the function applies the offset of the time zone assuming that inputdate value is provided in the target time zone. Thus as described in the MSDN documentation: GETUTCDATE() returns a datetime, which has no time zone offset information.
#Time zones time converter code#
The first line of your code contains the fault: SELECT GETUTCDATE() AT TIME ZONE 'GMT Standard Time' I feel like I'm missing something obvious - is there an easy way to take a datetimeoffset and return just the date/time part at that offset? SELECT CONVERT(datetime, Returns 02:27:54.020 I've tried three different approaches, none of which give me the result I'm looking for: SELECT Returns 01:27:54.0200000 +00:00 Next, I want to convert that to a datetime, which is what my applications expect. SET = (SELECT GETUTCDATE() AT TIME ZONE 'GMT Standard Time') The first step is to get a datetimeoffset, which I can successfully do as follows: DECLARE datetimeoffset At the time of running all of the commands below, the time in London was 3.27am. I'm just trying to get the current time in London as a datetime, adjusted for daylight saving. I am trying to use the new AT TIME ZONE syntax in SQL Server 2016 and Azure SQL.
