I updated the tzdata2026c patch in my openjdk 11.0.31 2026-04-21 LTS. However, when I ran the jShell commands to check the abbreviation, it still shows MST and MDT both. Are we expecting a new patch for the same? as offset is -06:00 but it shows MST.
I assume you're talking about the America/Edmonton timezone. Updating to TZDB 2026c should mean that America/Edmonton will be at -06 for the indefinite future, so if you're seeing -06 for current and future (i.e., winter) timestamps your UTC offsets should be good.
For time zone abbreviations like "MST" and "MDT", OpenJDK uses CLDR which has not yet been updated for America/Edmonton. As I understand it, CLDR runs on a 6-month release cycle and if the past is a guide their next release should arrive late October. Until then you may see confusing or inaccurate time zone abbreviations and localizations for America/Edmonton. Although we've been in contact with the CLDR folks, I don't know what they're doing about Edmonton. You can try contacting them yourself by following the instructions in <https://cldr.unicode.org/requesting_changes>.
In this period of confusion I suggest avoiding abbreviations like "MST" as they are becoming ambiguous. Use numeric offsets like "-06" instead. If you do that, it won't matter what TZDB and CLDR do about the abbreviations.
