Added: - calendar-sync--extract-tzid: extracts TZID from property lines - calendar-sync--convert-tz-to-local: converts using date command - Modified parse-timestamp to accept optional TZID parameter - Modified parse-event to extract and pass TZID through pipeline Includes 40 new tests covering extraction, conversion, and integration. 2025-12-02T13:55:21+00:00 Craig Jennings c@cjennings.net 2025-12-02T13:55:21+00:00 urn:sha1:703bc366cf8439a398362d98bef513ef98942fd4 Added multi-URL calendar sync supporting Google and Proton calendars. Each calendar syncs to separate file with per-calendar state tracking. Added 13 property-based tests for RRULE expansion. Total: 150 tests passing. 2025-11-17T00:09:17+00:00 Craig Jennings c@cjennings.net 2025-11-17T00:09:17+00:00 urn:sha1:d842e08de5600c90c2f9de93ca81aea32be9775a Implemented calendar-sync.el as a complete replacement for org-gcal, featuring: **Core Functionality:** - One-way sync from Google Calendar to Org (via .ics URL) - UTC to local timezone conversion for all event timestamps - Chronological event sorting (past → present → future) - Non-blocking sync using curl (works reliably in daemon mode) **Automatic Timezone Detection:** - Detects timezone changes when traveling between timezones - Tracks timezone offset in seconds (-21600 for CST, -28800 for PST, etc.) - Triggers automatic re-sync when timezone changes detected - Shows informative messages: "Timezone change detected (UTC-6 → UTC-8)" **State Persistence:** - Saves sync state to ~/.emacs.d/data/calendar-sync-state.el - Persists timezone and last sync time across Emacs sessions - Enables detection even after closing Emacs before traveling **User Features:** - Interactive commands: calendar-sync-now, calendar-sync-start/stop - Keybindings: C-; g s (sync), C-; g a (start auto-sync), C-; g x (stop) - Optional auto-sync every 15 minutes (disabled by default) - Clear status messages for all operations **Code Quality:** - Comprehensive test coverage: 51 ERT tests (100% passing) - Refactored UTC conversion into separate function - Clean separation of concerns (parsing, conversion, formatting, sorting) - Well-documented with timezone behavior guide and changelog **Migration:** - Removed org-gcal-config.el (archived in modules/archived/) - Updated init.el to use calendar-sync - Moved gcal.org to .emacs.d/data/ for machine-independent syncing - Removed org-gcal appointment capture template Files modified: modules/calendar-sync.el:442, tests/test-calendar-sync.el:577 Files created: data/calendar-sync-state.el, tests/testutil-calendar-sync.el Documentation: docs/calendar-sync-timezones.md, docs/calendar-sync-changelog.md
