For information about using the CAST and CONVERT functions with date and time data, see CAST and CONVERT (Transact-SQL) Converting datetimeoffset data type to other date and time types When you convert to date and time data types, SQL Server rejects all values it cannot recognize as dates or times. SQL Server data typeĭefault string literal format passed to down-level client The following table shows the type mapping between an up-level instance of SQL Server and down-level clients. Some down-level clients do not support the time, date, datetime2 and datetimeoffset data types. Backward compatibility for down-level clients The ANSI and ISO 8601 Compliance sections of the date and time topics apply to datetimeoffset. To convert a date to a corresponding datetimeoffset value in a target time zone, see AT TIME ZONE (Transact-SQL). ![]() For example, 10:10:00 is valid in UTC, but overflow in local time to the time zone offset +13:50. ![]() The detection of any invalid UTC or local (to the persistent or converted time zone offset) datetime value will raise an invalid value error. The given time zone offset will be assumed to be daylight saving time (DST) aware and adjusted for any given datetime that is in the DST period.įor datetimeoffset type, both UTC and local (to the persistent or converted time zone offset) datetime value will be validated during insert, update, arithmetic, convert, or assign operations. The time zone offset will be preserved in the database for retrieval. The data is stored in the database and processed, compared, sorted, and indexed in the server as in UTC. The default fractional seconds precision is 100ns (seven digits for the fractional part of the seconds). ![]() This value can be an integer with 0 to 7 (100 nanoseconds). The optional type parameter fractional seconds precision specifies the number of digits for the fractional part of the seconds. The time zone offset range follows the W3C XML standard for XSD schema definition and is slightly different from the SQL 2003 standard definition, 12:59 to +14:00. The valid range of time zone offset is from -14:00 to +14:00. This indicates whether the time zone offset is added or subtracted from the UTC time to obtain the local time. + (plus) or - (minus) is the mandatory sign for a time zone offset.mm is two digits, ranging from 00 to 59, that represent the number of additional minutes in the time zone offset.hh is two digits that range from 00 to 14 and represent the number of hours in the time zone offset.The time zone offset can be represented as hh:mm: For example, 12:30:30.12345 -07:00 should be represented as 19:30:30.12345Z.Ī time zone offset specifies the zone offset from UTC for a time or datetime value. This format by ISO definition indicates the datetime portion should be expressed in Coordinated Universal Time (UTC). Spaces are not allowed between the datetimeoffset and the datetime parts. These two formats are not affected by the SET LANGUAGE and SET DATEFORMAT session locale settings. ![]() datetimeoffset description Propertyĭatetimeoffset ĬREATE TABLE Table1 ( Column1 datetimeoffset(7) )ĭefault string literal formats (used for down-level client) Applies to: SQL Server Azure SQL Database Azure SQL Managed Instance Azure Synapse Analytics Analytics Platform System (PDW)ĭefines a date that is combined with a time of a day based on a 24-hour clock like datetime2, and adds time zone awareness based on UTC (Universal Time Coordinate or Greenwich Mean Time).
