DeepDiff Fails to Detect Timezone Changes in Arrays with ignore_order=True

[3schwartz]

Solution proposal for issue #516

Description

The deepdiff library is unable to detect timezone changes in datetimes within arrays.

When ignore_order=True and a datetime is present within an array, deepdiff uses an execution path that makes a DeepHash. Due to the implementation of datetime_normalize, all datetimes have their timezone set to UTC:

deepdiff/deepdiff/helper.py

Line 627 in c718369

obj = obj.replace(tzinfo=datetime.timezone.utc)

This behavior causes issues in our use case, as we rely on deepdiff to detect changes in datetime objects, including changes to their timezones.

Changes

Indent logic which replaces timezone to only affect those which has set truncate_datetime.
