Horizon: AgularJS pages do not display dates in system's timezone

[Kristine Bujold]

Brief Description
-----------------
Horizon's AngularJS pages (for example Images) does not display timestamp in system's timezone. The timezone used is the browser's.

Severity
--------
Minor

Steps to Reproduce
------------------
- If Timezone is not set under Settings (menu on the top right):
Set the controller's system timezone to a one different from UTC and the browser, for example "system modify --timezone America/Regina"
The Image timestamps (for example 'Created At') are displayed in the browser's timezone and not the system's timezone.

or

- If Timezone is set under Settings (menu on the top right):
Set Horizon's Settings Timezone to one that is different from UTC and the browser.
The Image timestamps (for example 'Created At') are displayed in the browser's timezone and not the Settings' timezone.

Expected Behavior
------------------
AngularJS pages should align with Django pages which use the timezone from the Horizon's cookie (which is set under the Settings menu on the top right), or if that is not set use the controller’s timezone.

Actual Behavior
----------------
The AngularJS pages use the browser's timezone.

Reproducibility
---------------
Reproducible

System Configuration

This is still a valid bug for starlingx even if the issue is with the underlying horizon implementation. I don't think marking this as "Invalid" is accurate. That being said, we wouldn't consider this a gating issue for starlingx.

I don't known why launchpad not auto update the fix patch's link. So I paste it here manual:

I have a patch to solve this problem, but it needs someone to review it.(https://review.opendev.org/#/c/678175/)

    AgularJS pages display dates using Horizon's Settings Timezone

    Horizon's AngularJS pages (for example Images and Keypairs)
    display dates using browser's timezone now. This change makes
    AngularJS pages use Horizon's Settings Timezone instead of
    browser's timezone and if Timezone is not set under Settings,
    AngularJS pages will display dates in 'UTC' timezone.
