Oracle Timestamp with Time Zone not being mapped to DateTimeOffset properly

I have a created date column with type of Timestamp with Time Zone in oracle. My C# model property type is a DateTimeOffset. It sets the value, but it loses the offset portion.

I tried writing my own custom type handler, but the object value that gets passed to the parse method is already a DateTime object, and has already lost the offset value of the data at that point.

The issue is reader => handler.Parse(type, reader.GetValue(startBound));

reader.GetValue(startBound) returns a DateTime at that point.

We need to be able to change it to reader.GetDateTimeOffset() or have some sort of lower level extension point.

Start at the mapping expression reader => handler.Parse(type, reader.GetValue(startBound)) and trace how the Oracle timestamp value reaches the type handler. Verify whether GetDateTimeOffset() or a lower-level extension point can preserve the offset, then confirm that a C# DateTimeOffset property receives it correctly. No test file or implementation path is named in the issue, so locate the relevant mapping tests before defining completion.
