What is the name of the time zone in India? I want to convert the Pacific time zone to the Indian time zone, which I tried with “(BeginDate to the `Pacific Standard Time` time zone) AT TIME ZONE `UTC` like PST2IST”. As for the form of the plan, it is no different from the datetimeoffset in general. If I have datetime values,. B for example in the AdventureWorks column Sales.SalesOrderHeader.OrderDate (for which I created an index named rf_IXOD), I run both queries: I live in Adelaide, Australia. And like more than a billion other people around the world, the people of Adelaide face a half-hour time zone. In winter we are UTC+9:30 and in summer UTC+10:30. Besides the fact that when you read this in the northern hemisphere, you have to remember that by “winter” I mean April to October. Summer is from October to April, and Santa claus sits on the beach with a cold drink and sweats through his thick red suit and beard. Unless it saves lives, of course. For the datetimeoffset type, THE UTC and the local datetime value (for persistent or converted time zone offset) are checked during insert, update, arithmetic, conversion, or assignment operations.
Detecting an invalid UTC or local datetime value (persistent or converted time zone offset) generates an invalid value error. For example, 9999-12-31 10:10:00 is valid in UTC, but overflows on the time zone difference +13:50 in local time. This creates the complete TSqlToolbox database, its tables, table data rows, functions, and primary/foreign key constraints. In the screenshot above, the FRANK-PC database server hosts the TSqlToolbox. Any database hosted by the FRANK-PC database server can use the TSqlToolbox functions. Unfortunately, the de facto standard for time zone names is the IANA time zone database. If I want to have the current time in Adelaide, I search for “Australia / Adelaide”. When I search for a flight, Qantas returns the departure and arrival times with a lag and “Australia/Adelaide”.
The same goes for GDS (Amadeus, Sabre) and websites like Flightstats. /* The adjusted time of the “interval interval” (between 02:00 and 03:00) is advanced by 1 hour and displayed with the DST offset (after the change of daylight saving time) */ SELECT CONVERT(datetime2(0), `2015-03-29T02:01:00`, 126) IN THE `Central European Standard Time` TIME ZONE; –Result: 29/03/2015 03:01:00 +02:00 Obviously, SQL Server has rounded the original data by reducing the nine digits to seven. This behavior is completely predictable because the DATETIME2 precision is 7 digits by default. Although this may initially lead to misunderstandings, as in the third case where we moved on to the next day, the behavior can be predicted and therefore avoided. However, the IANA/Olson time zone database has been refined to a specific narrow location, compared to the Microsoft Window time zone database, which is very varied. This Git project uses the IANA/Olson time zone database for SQL Server, but it appears that scenarios such as the “Spring Forward” and “Fall Back” daylight saving time transition are not included. github.com/mj1856/SqlServerTimeZoneSupport If you use GETUTCDATE() instead of GETDATE(), you get the current UTC date and time. So use GETUTCDATE() wherever you want to get the current server date when inserting or updating. Here`s an example: I`m only interested in the name, but still. And it`s interesting to see that there`s a time zone called “From Central W. Standard Time” that`s quarter of an hour. Go figure.
It is also worth mentioning that the places are designated by their standard time name, even though they currently respect summer time. Like Ulaanbaatar in this list above, which is not listed as Ulaanbaatar Daylight Time. This can launch people for a loop when they start using AT TIME ZONE. At this point, it becomes clear why it is useful to know the internal representation of each type of data. Based on what we have already mentioned in terms of the internal representation of DATETIME, DATETIME2, DATE and TIME, it becomes clear that none of them are actually sufficient for this work, since they do not specify a time zone that leads to ambiguous types. There is no way to distinguish whether timestamps are measured based on the local computer`s time zone, UTC, or server time. Sets a combined date to a time of day based on a 24-hour clock such as datetime2 and adds time zone knowledge based on Universal Time coordinate or Greenwich Mean Time (UTC). For more information about converting between time zones and how people like Aaron handled daylight saving time, check out the links below: It`s probably fair enough. I mean – by the time he creates the plan, he won`t have asked the registry for the information he needs, so he really doesn`t know how much he`s supposed to estimate. .
