As per the online guide here User Management Users - PBX GUI - Documentation it says that I can change the timezone from the User Details tab inside User Management. However, when I create a user and open User Details I can’t find that option.
FreePBX 220.127.116.11 Current Asterisk Version: 11.23.1
Extension Settings 13.0.4
User Management 18.104.22.168
If you meant adding this feature in 13? Then no, FreePBX 13 is soon going to be EOL, no new things are being worked on 13.
In fact, FreePBX 15 alpha was released in August, which means that it is going stable sooner than later… So consider upgrading to 14.
