Further customizations

Code:

var force_preference = true;
- If the value is
  
  Code:
  
  true
  
  :
  - in the profile, time zones that are not in the preferences list are not displayed,
  - when the preferences profile page is open, if the user is in a time zone that is not in the preferences list the script will try to change it to a time zone in the preferences list corresponding to the time when the system operating (windows, android, ...),
  - when the member has the required number of messages for the time zone to be set automatically once, if the current time zone is not in the preference list, even if it has the correct time difference that the operating system can change.
- If the value is
  
  Code:
  
  false
  
  and the time zone has the same time difference as the operating system, it will not be changed.
Code:

var force_if_no_match = false;

If the time zone is set automatically and none matches the operating system time difference, true will choose the first time zone in the reference list. With false in this case the time zone will not be changed.
Code:

var auto_set_max_messages = 0;

This is the maximum number of messages a member must have in order for the time zone to be automatically set once (if they switch browsers or switch to private browsing, it will run again).

Putting 0 this will only be done for members with 0 messages (this allows you to change the time zone only for new ones without affecting those who have an account). Putting for example a negative number (-1) will be disabled. Putting a large number (999999999 for example) should apply to all members.
Rename

Code:

// timezone with given name will be renamed as specified var rename = { Toronto: "Montréal", };

A list of visual replacements to do, for example this will replace "Toronto" with "Montreal", if we want to add "Thunder_Bay" with "Quebec" we can add a line:

Code:

var rename = { Thunder_Bay: "Québec", Toronto: "Montréal", };

The left part must be exactly what is to the right of / in the list above. Also, since the change is visual only, it is imperative that the replaced name actually matches the same summer and winter time zone as the replacement.

To test the script, you can change

Code:: force_preference

Code:: false

to insert a time zone that is not in the preferences list, then reset

Code:: force_preference

Code:: true

and reopen the "Profile"> "Preferences" page, the script should:

Take the first time zone in the preference list which corresponds to the time difference of the operating system,
if there is none and

Code:

force_if_no_match

is

Code:

true

, get the first time zone from the preference list,
if force_if_no_match is
, the first time zone in the list will be displayed, but will only be saved by pressing the "Save" button.

If you want to test whether a member's time zone is automatically put below the

Code:: auto_set_max_messages

message count , you need to enter an Incognito window with a user who has configured the maximum number of messages.
