The first switch after the change is expected to take place on last Friday of April. The upstream tzdata 2023a release already reflects this change. The 2023a release contains the following changes: * Egypt now uses DST again, from April through October. * This year Morocco springs forward April 23, not April 30. * Palestine delays the start of DST this year. * Much of Greenland still uses DST from 2024 on. The 2023c release reverts the changes done in 2023b. [ Test Plan ] Test cases were added to the autopkgtest to cover the testing: * python: test_2023a * python: test_2023c * python: test_systemv_timezones (for releases <= 20.04 LTS) * python-icu: test_2023a (only for kinetic, jammy, focal) So the test plan is to check that the autopkgtest succeeds. Alternatively the python test_2023a can be run manually: * Set system timezone to Egypt (e.g. Africa/Cairo). * Set system time to 2023-04-27 23:59. * Wait and observe what happens at 2023-04-28 0:00 [Test Case for releases <= 20.04 LTS] Additionally, an upstream update of tzdata removed the 'old' SystemV timezones, so we should ensure that they are kept in Ubuntu 20.04 LTS and earlier releases. This is done by the test_systemv_timezones test case or can be checked manually with the following: diff <(zdump -v America/Phoenix | cut -d' ' -f2-) <(zdump -v SystemV/MST7 | cut -d' ' -f2-) [ Where problems could occur ] * Systems with incorrect timezone set (e.g. located outside of Egypt but still using Egyptian time) may observe unexpected time shift. [ Other Info ] The autopkgtest for chrony is flaky on jammy and kinetic (see bug #2002910). * More information with sources: https://en.wikipedia.org/wiki/Daylight_saving_time_in_Egypt#:~:text=Daylight%20saving%20time%20(DST)%20has,(DST)%20as%20of%202023.
