Preserve timezone offset when parsing datetime properties

[jan-guenter]

Description

For my use case I would highly prefer to have the timezone offset preserved in the resulting datetime objects when properties are parsed.

Type of change

• Breaking change (fix or feature that would cause existing functionality to not work as expected)

This change could break code that does not handle the timezone offset of the datetime data type.

How Has This Been Tested?

Since there are no unit test, I only tested the code in my specific use case.
