With yesterday's updates, Canonical made some changes to the upcoming Ubuntu 12.10 (Quantal Quetzal) operating system, regarding the Date and Time Indicator.
After revamping the Session menu Indicator last week, the Ubuntu developers added sorting support to the multiple time zones function in the Date and Time Indicator of the upcoming Ubuntu 12.10 operating system.
Therefore, users who have added multiple time zones can now easily sort them by name or by time, accessing the "Time & Date Settings -> Clock tab -> Choose Locations" dialog.
Moreover, it appears that a new function has been added to the Date and Time Indicator, called Time in auto-detected location.If checked, it will automatically insert the current location of the Ubuntu machine.
However, considering that Ubuntu 12.10 is in Alpha development stage, everything is subject to change. We will keep you informed about future changes.
