En SQL Server 2008 puedes usar el datetimeoffset
tipo de datos.
SELECT [Result] = CONVERT(datetimeoffset, '2005-08-08T00:01:00+01:00', 127)
Salida:
Result
----------------------------------
2005-08-08 00:01:00.0000000 +01:00
En SQL Server 2005 y antes, puede calcular la fecha UTC y el desplazamiento:
SELECT [LocalDate], [OffsetMinutes], [UtcDate]
FROM
(
SELECT [IsoDate] = '2007-08-08T00:01:00+01:00'
) A
OUTER APPLY
(
SELECT [LocalDate] = CONVERT(datetime, LEFT([IsoDate], 19), 126)
, [OffsetMinutes] =
CASE SUBSTRING([IsoDate], 20, 1)
WHEN '+' THEN +1
WHEN '-' THEN -1
END
* DATEDIFF(minute, 0,
CAST(SUBSTRING([IsoDate], 21, 5) + ':00' AS datetime))
WHERE [IsoDate] LIKE '____-__-__T__:__:__[+-]__:__'
) B
OUTER APPLY
(
SELECT [UtcDate] = DATEADD(minute, -[OffsetMinutes], [LocalDate])
) C
Salida:
LocalDate OffsetMinutes UtcDate
