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:

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:

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
