Implementation Summary: Timezone Fix + Per-Space Settings

Overview

Fixed timezone display issues and added per-space scheduling settings to the space booking system.

Changes Implemented

Part A: Frontend Timezone Fix ✅

File: frontend/src/utils/datetime.ts

• Added ensureUTC() function to handle naive datetime strings from backend
• Applied ensureUTC() to all new Date() calls in:
  • formatDateTime()
  • formatTime()
  • formatDateTimeWithTZ()
  • isoToLocalDateTime()

File: frontend/src/views/Dashboard.vue

• Imported ensureUTC from utils
• Applied to booking date comparisons in upcomingBookings computed property

Impact: MyBookings now correctly shows times in user's timezone (e.g., 10:00-17:00 Bucharest instead of 08:00-15:00 UTC).

---

Part B: Per-Space Scheduling Settings (Database) ✅

File: backend/app/models/space.py

• Added 4 nullable columns:
  • working_hours_start (Integer)
  • working_hours_end (Integer)
  • min_duration_minutes (Integer)
  • max_duration_minutes (Integer)

File: backend/app/schemas/space.py

• Added 4 optional fields to SpaceBase and SpaceResponse

File: backend/migrations/004_add_per_space_settings.sql

• Created migration (already applied to database)

Impact: Spaces can now override global settings. NULL = use global default.

---

Part C: Timezone-Aware Validation ✅

File: backend/app/services/booking_service.py

• Imported Space model and timezone utilities
• Added user_timezone parameter to validate_booking_rules()
• Load per-space settings with fallback to global
• Convert UTC times to user timezone for working hours validation
• Fix max bookings per day to use local date boundaries

File: backend/app/api/bookings.py Updated 6 endpoints to pass user_timezone:

1. POST /bookings (create) - Line ~251
2. POST /bookings/recurring - Line ~376
   • Also fixed: Now converts local times to UTC before storage
3. PUT /bookings/{id} (update) - Line ~503
4. PUT /admin/.../approve - Line ~682
   • Uses booking owner's timezone
5. PUT /admin/.../update - Line ~865
   • Uses booking owner's timezone
6. PUT /admin/.../reschedule - Line ~1013
   • Uses booking owner's timezone

Impact:

• Working hours validation now uses user's local time (9:00 Bucharest is valid, not rejected as 7:00 UTC)
• Per-space settings are respected
• Recurring bookings now store correct UTC times

---

Part D: Admin UI for Per-Space Settings ✅

File: frontend/src/views/Admin.vue

• Added form section "Per-Space Scheduling Settings"
• Added 4 input fields with placeholders indicating global defaults
• Updated formData reactive object
• Updated startEdit() to load space settings
• Updated resetForm() to clear settings
• Added CSS for form-section-header, form-row, and help-text

File: frontend/src/types/index.ts

• Extended Space interface with 4 optional fields

Impact: Admins can now configure per-space scheduling rules via UI.

---

Testing Checklist

Timezone Display

• User with Europe/Bucharest timezone sees correct local times in MyBookings
• Booking created at 09:00 Bucharest shows as 09:00 (not 07:00)

Working Hours Validation

• Booking at 09:00 Bucharest (07:00 UTC) is accepted (not rejected by 8-20 rule)
• User sees error message with correct timezone-aware hours

Per-Space Settings

• Create space with custom working hours (e.g., 10-18)
• Booking outside custom hours is rejected
• Space without settings uses global defaults
• Admin UI displays and saves per-space settings correctly

Recurring Bookings

• Recurring bookings now store correct UTC times
• Bookings created for multiple occurrences have consistent timezone handling

Known Limitations

1. SQLite: COMMENT ON COLUMN not supported (documented in migration file)
2. Backward Compatibility: Existing bookings created before fix may have incorrect times (data migration not included)

---

Next Steps

1. Run frontend ESLint: cd frontend && npx eslint src/utils/datetime.ts src/views/Dashboard.vue src/views/Admin.vue
2. Run backend tests: cd backend && pytest (if tests exist)
3. Manual testing per checklist above
4. Consider data migration for existing bookings if needed
