+2026.07.20 – Remove timezone abbreviation from !time response.
+
+- `!time` now outputs date and time only (`YYYY-MM-DD HH:MM:SS`) without the timezone abbreviation, keeping IRC responses shorter and cleaner.
+- Removed 60 lines of dead timezone abbreviation-matching code from `tz_format()` (previously mapped 45 IANA timezone names to abbreviations like CEST, EDT, JST, etc.).
+- Updated README.md output format to reflect the change.
+- Added `tzdata` to README.md requirements as optional (without it, `!time` falls back to 45 built-in timezones).
+- Version bumped to 0.35.6.
+
 2026.07.20 – Fix !time to work without tzdata.
 
 - Rewrote `!time` to try the system `localtime_r()` first, then fall back to a built-in timezone table with 45 IANA zones and simplified DST rules when the system can't resolve timezones (e.g. no `tzdata` installed). This means `!time Australia/Sydney` now shows correct AEST/AEDT even on minimal systems.
