# Shift Times Correction - Complete ✅
|
|
|
|
## Issue
|
|
Shift times were incorrectly set:
|
|
- AM shift was showing 7:00 AM to 8:00 PM (should be 7:00 PM)
|
|
- PM shift was showing 8:00 PM to 7:00 AM (should start at 7:00 PM)
|
|
|
|
## Correct Shift Times
|
|
|
|
### AM Shift (Day Shift)
|
|
- **Start Time**: 7:00 AM
|
|
- **End Time**: 7:00 PM (same day)
|
|
- **Duration**: 12 hours
|
|
- **Production Hours**: 8:00 AM to 7:00 PM
|
|
|
|
### PM Shift (Night Shift)
|
|
- **Start Time**: 7:00 PM
|
|
- **End Time**: 7:00 AM (next day)
|
|
- **Duration**: 12 hours
|
|
- **Production Hours**: 8:00 PM to 7:00 AM
|

## Fix Applied
|
|
|
|
### File Modified
|
|
`app/api/shifts/route.ts`
|
|
|
|
### Changes Made
|
|
|
|
**Before:**
|
|
```typescript
|
|
const date = new Date(shiftDate)
|
|
const startTime = name === "AM" ? new Date(date.setHours(7, 0, 0)) : new Date(date.setHours(20, 0, 0))
|
|
const endTime = name === "AM" ? new Date(date.setHours(19, 0, 0)) : new Date(date.setHours(7, 0, 0))
|
|
```
|
|
|
|
**Issues:**
|
|
- PM shift started at 8:00 PM (20:00) instead of 7:00 PM (19:00)
|
|
- PM shift end time was on the same day, not next day
|
|
- Date mutation caused issues
|
|
|
|
**After:**
|
|
```typescript
|
|
const shiftDateObj = new Date(shiftDate)
|
|
|
|
let startTime: Date
|
|
let endTime: Date
|
|
|
|
if (name === "AM") {
|
|
// AM shift: 7:00 AM to 7:00 PM (same day)
|
|
startTime = new Date(shiftDateObj)
|
|
startTime.setHours(7, 0, 0, 0)
|
|
|
|
endTime = new Date(shiftDateObj)
|
|
endTime.setHours(19, 0, 0, 0)
|
|
} else {
|
|
// PM shift: 7:00 PM to 7:00 AM (next day)
|
|
startTime = new Date(shiftDateObj)
|
|
startTime.setHours(19, 0, 0, 0)
|
|
|
|
endTime = new Date(shiftDateObj)
|
|
endTime.setDate(endTime.getDate() + 1) // Next day
|
|
endTime.setHours(7, 0, 0, 0)
|
|
}
|
|
```
|
|
|
|
**Fixes:**
|
|
- ✅ PM shift now starts at 7:00 PM (19:00)
|
|
- ✅ PM shift end time is on next day
|
|
- ✅ Proper date handling without mutation
|
|
- ✅ Clear comments for each shift type
