Question

我一直在努力将应用程序转换为使用NoDateTime库，并且遇到了即时属性映射的问题。

根据文档：http://www.npgsql.org/doc/types/nodatime.html 我应该能够将Instant映射到Postgresql时间戳我正在使用conn.TypeMapper.UseNodaTime（）; 我得到的错误是： 42804 列 instantdate 的类型为timestamp，没有时区，但表达式的类型为bytea

使用nhibernates属性映射属性，对此属性未设置任何属性（将属性设置为timestamp时会出现不同的错误）。

任何人都可以指出我需要做些什么才能使它工作？

使用：

休眠4.12
nhibernate.mapping.attributes
4.0 npgsql 4.0.1 更新-将nhibernate和nhibernate.mappin.attribute更新为最新属性，对于即时和其他NodaTime类型仍然会发生。它们似乎都映射到nhibernate中的字节数组。将属性类型设置为时间戳也不起作用。

生成的插入语句：

 NHibernate.IDbCommand: INSERT INTO TestDates (InstantDate, LocalDate, ZonedDate, Id) VALUES (:p0, :p1, :p2, :p3);:p0 = 0x0001000000FFFFFFFF01000000000000000C020000004B4E6F646154696D652C2056657273696F6E3D322E332E302E302C2043756C747572653D6E65757472616C2C205075626C69634B6579546F6B656E3D343232366166653064396232393664310501000000104E6F646154696D652E496E7374616E740200000004646179...

将NodaTime与Nhibernate.Mapping和Postgresql一起使用-即时
