# Navigation Bar Time Integration

## 🎯 Overview

The navigation bar (`components/main-nav.tsx`) currently displays a static time that doesn't refresh. This document outlines how to integrate it into the unified refresh system.

## 🔍 Current Issue

**File**: `components/main-nav.tsx` (lines 228-231)

```typescript
// Current code - STATIC (doesn't refresh)
const now = new Date();
const formattedDate = format(now, "d MMMM yyyy", { locale: fr });
const formattedTime = format(now, "HH:mm");
```

**Problem**: Time is calculated once when component renders and never updates.

## ✅ Solution

### Step 1: Create Time Component

**File**: `components/main-nav-time.tsx` (✅ Already created)

This component:
- Uses `useState` to track current time
- Uses `useUnifiedRefresh` hook for 1-second updates
- Properly cleans up on unmount
- No API calls needed (client-side only)

### Step 2: Update MainNav Component

**File**: `components/main-nav.tsx`

**Changes needed**:

1. **Import the new component**:
```typescript
import { MainNavTime } from './main-nav-time';
```

2. **Remove static time code** (lines 228-231):
```typescript
// DELETE THESE LINES:
// Format current date and time
const now = new Date();
const formattedDate = format(now, "d MMMM yyyy", { locale: fr });
const formattedTime = format(now, "HH:mm");
```

3. **Replace time display** (lines 294-298):
```typescript
// BEFORE:
{/* Center - Date and Time */}
<div className="hidden md:flex flex-col items-center">
  <div className="text-white/80 text-xs">{formattedDate}</div>
  <div className="text-white text-sm font-medium">{formattedTime}</div>
</div>

// AFTER:
{/* Center - Date and Time */}
<MainNavTime />
```

### Step 3: Verify Integration

After changes:
- ✅ Time updates every second
- ✅ Uses unified refresh system
- ✅ Proper cleanup on unmount
- ✅ No memory leaks
- ✅ Consistent with other widgets

## 📊 Benefits

1. **Real-time clock**: Time updates every second
2. **Unified system**: Uses same refresh manager as widgets
3. **Memory safe**: Proper cleanup prevents leaks
4. **Consistent**: Same pattern as other components
5. **Maintainable**: Centralized refresh logic

## 🔧 Technical Details

### Refresh Configuration

- **Resource**: `navbar-time`
- **Interval**: 1000ms (1 second)
- **Priority**: `high` (real-time display)
- **API Calls**: None (client-side only)
- **Cleanup**: Automatic via `useUnifiedRefresh`

### Integration with Refresh Manager

The time component registers with the refresh manager:

```typescript
useUnifiedRefresh({
  resource: 'navbar-time',
  interval: REFRESH_INTERVALS.NAVBAR_TIME, // 1000ms
  enabled: true, // Always enabled
  onRefresh: async () => {
    setCurrentTime(new Date());
  },
  priority: 'high',
});
```

## ✅ Implementation Checklist

- [x] Create `components/main-nav-time.tsx`
- [x] Add `NAVBAR_TIME` to refresh intervals
- [x] Add `navbar-time` to refreshable resources
- [ ] Update `components/main-nav.tsx` to use new component
- [ ] Test time updates correctly
- [ ] Verify cleanup on unmount
- [ ] Test with multiple tabs

## 🎯 Expected Result

After implementation:
- Time updates smoothly every second
- No performance impact
- No memory leaks
- Consistent with unified refresh system
