I have a DateTime property in my class which is set to a date but no time, e.g. Dec 7, 1980 0:00:00.

{{public DateTime DateOfBirth { get; set; }}}

The property is auto serialized (no bson attributes or whatever) and the expected value in the collection is:

1980-12-07T00:00:00.000+00:00

However what is written to the database instead is:

1980-12-06T23:00:00.000+00:00
