### Problem Description

We have problems with the new property "DateTimeReference" because it is empty.
Please have a look at this PR where we implemented a workaround: https://github.com/dataplat/dbatools/pull/9716

It would be nice to have some more background information so that we can change our code correctly. Or is this a bug on your side?

### LINQPad Example or Reproduction Steps

```
$script:faker = New-Object Bogus.Faker('en')

Start by reviewing the DateTimeReference property on Bogus.Faker and the workaround in dbatools PR #9716. Reproduce the null value using the supplied PowerShell/LINQPad example, then determine the intended behavior and document or fix it so the property has a clear, verified result.
