Selection of Time Zone in user preferences does not stick [5.2]

[rileydog]

I am having trouble with the timezone setup.

1. under personal preferences, when I select a timezone and press save, it reverts to "none selected.

This issue discussed here: https://community.plone.org/t/is-setting-the-time-zone-supposed-to-change-the-time-recorded-on-the-site/1303

I confirmed this bug with @cewing

Bumping this because it looks orphaned and has no assignees. Bug still active in Plone 5.0.6. When will this be addressed?

I can confirm that this bug is still in Plone 5.0.7. Doesn't look like any progress has been made.

In 5.1.2 the settings stick in the settings page, but my content still shows UTC times. I set it to Los Angeles.

I am working on this.
The problem is that this adapter wants to set a property that is not in the memberdata properties and this fails silently:
https://github.com/plone/plone.app.users/blob/575fe2bb60201f795387f322dd5318b86efd62c0/plone/app/users/browser/account.py#L71-L78
This appears to be a valid fix:

ale@avo:~/Code/plone/projects/coredev/6.0/src/plone.app.users$ cat plone/app/users/profiles/default/memberdata_properties.xml
<?xml version="1.0"?>
<object name="portal_memberdata" meta_type="PlonePAS MemberData Tool">
 <property name="timezone" type="string"></property>
</object>

I will work on a patch.

A quick fix for this is to go to the portal_menberdata tool (e.g. https://demo.plone.org/portal_memberdata/manage_propertiesForm) and add the timezone property (see the form at the bottom of the page).

It can also be done with this Python code:

I am reopening it because on Plone 5.2. this is still an issue
