Symptoms

There have been changes to timezone data that impact tzdata packages: * Mongolia no longer observes Daylight Saving Time (DST). * The Magallanes Region of Chile has moved from a UTC-04/-03 scheme to UTC-03 all year. Starting 2017-05-13 at 23:00, the clocks for the Magallanes Region will differ from America/Santiago.

Impact

Timezone data provided in tzdata will not match the area's time. Clocks for the Magallanes Region will differ from America/Santiago (its current timezone).

Conditions

-- Mongolia during DST portion of the year. -- Comparing clock times in the America/Santiago zone with those in the Magallanes Region.

Workaround

None.

Fix Information

To accommodate for Mongolia no longer observing DST, the new America/Punta_Arenas zone was created. Changes were also made to support other timezone changes. * The zone1970.tab file has been added to the list of files to be installed with the tzdata packages installation. Note: Users of tzdata are advised to upgrade tzdata to zdata-2017b-1.el6
