** Description changed: New timezone data, with the following timezones impacted: - Palestine transitions are now Saturdays at 02:00. This means 2022 falls back 10-29 at 02:00, not 10-28 at 01:00. - Simplify three Ukraine zones into one. - Jordan and Syria switch from +02/+03 with DST to year-round +03. icu update to 2022e: https://unicode-org.atlassian.net/browse/ICU-22178 + + Verification is done with 'zdump'.
