fluent nhibernate on postgresql: define default column value to current UTC date?

Question

How does one do this?

I had assumed it was something like this:

Map(x => x.PersistedTimeStamp)
    .CustomType<UtcDateTimeType>()
    .Generated.Insert();

...this does nothing, however.

Answer 1

Generated.Insert() only means "the DB will generate this value on insert; retrieve it for me afterwards"

Instead, just set the property to DateTime.UtcNow in the constructor.
