--- Comment #31 from Martin Renvoize (ashimema) <[email protected]> --- Created attachment 191360 --> https://bugs.koha-community.org/bugzilla3/attachment.cgi?id=191360&action=edit Bug 37707: Fix timezone handling in place_booking modal This patch fixes timezone inconsistencies in the place_booking modal that caused dates to shift when the server and browser are in different timezones. Issues Fixed: 1. Date index creation used .toISOString().split("T")[0] which converted to UTC, causing western timezone dates to appear on wrong calendar days 2. Date comparisons mixed flatpickr.parseDate() and dayjs() without normalizing to start-of-day 3. Booking overlap detection had inconsistent timezone handling Changes: - Replace .toISOString().split("T")[0] with dayjs().format('YYYY-MM-DD') to maintain browser timezone consistency - Normalize all date comparisons to start-of-day using dayjs().startOf('day') - Use dayjs() consistently for parsing RFC3339 datetime strings from API - Add explicit .startOf('day') and .endOf('day') for API submission clarity These changes ensure: - Bookings display on correct calendar days regardless of browser timezone - Multi-day bookings span the correct number of days - Conflict detection works consistently across all timezones - Item availability calculations are accurate - Future hourly booking support is preserved (time components maintained) Test plan: 1. Set browser to PST (UTC-8), server to UTC 2. Create a booking for January 15 3. Verify booking displays on Jan 15 only (not Jan 15-16) 4. Create a 3-day booking (Jan 15-17) 5. Verify displays on exactly 3 days 6. Test conflict detection with overlapping bookings 7. Repeat tests with browser in HST (UTC-10) and NZDT (UTC+13) -- You are receiving this mail because: You are watching all bug changes. _______________________________________________ Koha-bugs mailing list [email protected] https://lists.koha-community.org/cgi-bin/mailman/listinfo/koha-bugs website : http://www.koha-community.org/ git : http://git.koha-community.org/ bugs : http://bugs.koha-community.org/
