El intervalo de tiempo devuelto incluye cualquier diferencia debido a la aplicación de reglas de ajuste a la zona horaria actual. Difiere de la BaseUtcOffset propiedad , que devuelve la diferencia entre la hora universal coordinada (UTC) y la hora estándar de la zona horaria y, por lo tanto, no tiene en cuenta las reglas de ajuste.

Si la dateTime propiedad del Kind parámetro no corresponde al objeto de zona horaria, este método realiza la conversión necesaria antes de devolver un resultado. Por ejemplo, esto puede ocurrir si la Kind propiedad es DateTimeKind.Local pero el objeto de zona horaria no es la zona horaria local. Si dateTime es ambiguo o si la hora convertida es ambigua, este método interpreta la hora ambigua como una hora estándar. Si dateTime no es válido, este método devuelve un TimeSpan objeto que refleja la diferencia entre utc y la hora estándar de la zona horaria.

El TimeZoneInfo.GetUtcOffset(DateTime) método es similar en funcionamiento al GetUtcOffset método de la TimeZone clase .
