All backend timestamps used datetime.now() (server local time) or the
deprecated datetime.utcnow(). The frontend's parseUTCDate() assumes
timestamps without timezone indicators are UTC and appends 'Z', so
stored timestamps were off by the timezone offset when the container's
timezone wasn't UTC.
Backend: replaced datetime.now() and datetime.utcnow() with
datetime.now(timezone.utc) across 16 files (~80 call sites) for all
database fields and DB comparisons. Cosmetic timestamps (filenames,
user-facing local time formatting) intentionally left as local time.
Frontend: replaced 13 new Date(backendTimestamp) calls with
parseUTCDate() across 8 files to correctly interpret UTC timestamps.
Slicer protocol handlers (bambustudio://, orcaslicer://) launch the
slicer app which fetches files via HTTP but cannot send auth headers.
The global auth middleware returned 401, causing "importing failed."
Add short-lived, single-use download tokens: the frontend fetches a
token via authenticated POST, then builds a /dl/{token}/{filename} URL
the slicer can access without auth headers. Tokens are validated
server-side (5-min expiry, single-use). Applies to archive files,
source 3MFs, and library files.
Also fix platform-specific URL formats to match slicer source code:
- macOS: bambustudioopen:// with encodeURIComponent
- Windows/Linux: bambustudio://open?file= (was wrongly using macOS scheme on Linux)
- OrcaSlicer: orcaslicer://open?file=
- Add formatStorageSize helper in FileManagerModal to display storage
in GB/MB instead of raw bytes
- Show "Overdue" label for queue items whose scheduled time has passed
by more than 1 minute
- Fix missing "in" prefix for English inDays translation
- Fix swapped justNow/now translations in Italian locale
- Fix whitespace formatting for waiting key across all locales
- Add trailing newline to date.ts and date.test.ts
refactor(utils): consolidate date and file size formatting

- Remove duplicate formatDuration & formatETA functions, now imported from utils/dates
- Remove formatTime (duplicate of formatDuration)
- Update formatETA to support optional i18n translation
- Update translation: common.tomorrow
Backend:
- Add dual external spool support for H2D (vt_tray as list: Ext-L/Ext-R)
- Add cloud filament ID map endpoint (/cloud/filament-id-map)
- Fix RFID spool data erased by periodic AMS updates (skip tag matcher
for RFID-tagged trays)
- Fix AMS slot config overwrites RFID spool state
- Fix K-profile selection corrupts existing profiles on X1C/P1S
- Resolve K-profiles filament name via cloud filament ID map
- Update print scheduler and usage tracker for dual external spools
Frontend:

presets filtered by @BBL model suffix and compatible_printers)
- Add pre-population for configured slots (preset, color, K-profile)
- Add K-Profiles view with accurate filament name resolution
- Internationalize all ConfigureAmsSlotModal strings (en/de/fr/it/ja — 21 keys)
- Add 5 new ConfigureAmsSlotModal tests (model filtering, pre-selection,
color pre-population, i18n)
- Update PrintersPage for dual external spool rendering
Docs:
- Update CHANGELOG, README, website features, and wiki AMS docs
AMS-HT global tray ID was calculated as ams_id * 4 (= 512 for unit 128)
but AMS-HT uses the raw ams_id directly since it has a single tray.
The backend misidentified 512 as an external spool, producing wrong
ams_mapping2. Fixed in 4 locations: frontend getGlobalTrayId(), backend
start_print() ams_mapping2 builder, print scheduler, and Spoolman tracking.
Users can now choose their preferred slicer (Bambu Studio or OrcaSlicer)
in Settings → General. All "Open in Slicer" buttons across Archives,
3D Preview, and context menus use the correct protocol for the selected
slicer. OrcaSlicer uses orcaslicer://open?file=<URL> on all platforms;
Bambu Studio uses bambustudio:// (Windows) or bambustudioopen:// (macOS/
Linux). Default remains Bambu Studio for backward compatibility.
Remove vestigial _debug_logging_enabled and _debug_logging_enabled_at
globals from support.py (written but never read; DB is queried directly).
Simplify hue classification in PrintersPage.tsx and colors.ts by removing
always-true h < 345 checks and dead 'Unknown' fallbacks. Narrow
getWifiStrength param type to remove always-false null guard.
Date input for scheduled prints was swapping month and day for European
users because:
1. EU format only accepted "/" separator, not "." which is common in
European locales (e.g., "5.2.2026" for Feb 5th)
2. System format fell back to new Date() which interprets ambiguous
dates in US format
Changes:
- Added splitDateParts() helper to accept /, ., and - separators
- Updated parseDateInput() to use proper locale detection for system
format instead of relying on Date constructor
- All explicit formats (us, eu, iso) now accept any of the three
separators
Closes#233
Issue #233: Respect user date/time format in queue scheduler
- Replace native datetime-local input with custom text inputs
- Add date parsing/formatting utilities for US, EU, ISO, and system formats
- Add calendar button that opens native picker for convenience
- Pass dateFormat and timeFormat settings to ScheduleOptionsPanel
- Show format-appropriate placeholders (MM/DD/YYYY, DD/MM/YYYY, etc.)
Closes#233
- Moved BAMBU_HEX_COLORS mapping and getColorName()/hexToColorName() functions to a shared location

- Added state for showFilamentMapping, isRefreshing, manualMappings
- Added queries for filament requirements and printer status

Closes#75
Problem: The backend stores timestamps in UTC, but when sending them to the frontend without timezone indicators, JavaScript interprets them inconsistently. Users saw UTC times displayed directly instead of converted to their local timezone (e.g., America/New_York).
Solution implemented:
1. Created /frontend/src/utils/date.ts with utilities:
- parseUTCDate(dateStr) - Parses backend timestamps as UTC by appending 'Z' to strings without timezone indicators
- formatDate(dateStr, options) - Formats UTC timestamps to local date/time
- formatDateOnly(dateStr, options) - Formats UTC timestamps to local date-only
2. Updated 15 frontend files to use the new utilities:
- ArchivesPage.tsx - Archive cards and list view dates
- PrintersPage.tsx - Last print date
- SettingsPage.tsx - API key last used date
- QueuePage.tsx - Scheduled print times
- ProjectDetailPage.tsx - Due dates and timeline
- ProfilesPage.tsx - Relative time display
- CalendarView.tsx - Calendar grouping by local date
- NotificationLogViewer.tsx - Log timestamps
- NotificationProviderCard.tsx - Last success date
- AMSHistoryModal.tsx - Chart data timestamps
- FilamentTrends.tsx - Usage data grouping
- PrinterQueueWidget.tsx - Queue item dates
- Add utils/slicer.ts with OS detection for protocol handler
- Windows: bambustudio://, macOS/Linux: bambustudioopen://
- Update all usages in ArchivesPage.tsx and ModelViewerModal.tsx
