+# Timezone Fix for ANNOTATE Charts
+
+## Problem
+Charts showed 2-hour offset between:
+- Candle data (from exchange in UTC)
+- Predictions/ghost candles (timestamped in local EET time)
+- Trade annotations/actions (timestamped in local EET time)
+
+## Root Cause
+System timezone: **EET (UTC+2)**
+- Exchange data: **UTC**
+- Python code: Used `datetime.now()` which returns **local time (EET)**
+- Result: 2-hour mismatch on charts
+
+## Solution Applied
+
+### 1. Python Backend Changes
+
+**Updated Files:**
+1. `ANNOTATE/core/annotation_manager.py`
+   - Changed `datetime.now()` → `datetime.now(pytz.UTC)`
+   - Lines: 49, 99, 454
+
+2. `ANNOTATE/web/app.py`
+   - Added `from datetime import datetime, timezone`
+   - Changed `datetime.now()` → `datetime.now(timezone.utc)`
+   - Line: 2451
+
+3. `ANNOTATE/core/real_training_adapter.py`
+   - Changed all `datetime.now()` → `datetime.now(timezone.utc)`
+   - Lines: 2146, 2875, 3140, 3161 (ghost candle predictions)
+
+### 2. JavaScript Frontend Changes
+
+**Updated File:**
+- `ANNOTATE/web/static/js/chart_manager.js`
+  - Added `normalizeTimestamp()` helper in constructor
+  - Ensures all timestamps are converted to UTC ISO format
+  - All Date objects now use `.toISOString()` for UTC consistency
+
+## Result
+- ✅ All timestamps now in UTC
+- ✅ Candles, predictions, and annotations aligned on same timeline
+- ✅ No more 2-hour offset
+
+## Testing
+1. Restart ANNOTATE application
+2. Create new annotations
+3. Verify predictions appear at correct time
+4. Verify ghost candles align with real candles
+
+## Notes
+- Existing annotations in database remain in local time (will show correctly once converted on read)
+- New annotations are stored in UTC
+- Charts now display all timestamps consistently in UTC
