Verifying Correct Times

Step-by-Step Verification

Step 1: Pick a specific flight

Note: Flight number (e.g., OS 801)
Note: Time shown on LobbyFlight

Step 2: Check official source

Go to airport website
Find same flight
Note the official time

Step 3: Compare

Same? → Everything correct
Different? → Check timezone offset
Offset = Timezone issue

Common Timezone Offsets

If times are offset by exactly these amounts:

Technical Diagnosis

Check Browser Timezone

// In browser console (F12 → Console):

// Device timezone
console.log(Intl.DateTimeFormat().resolvedOptions().timeZone);

// Current offset from UTC (in minutes)
console.log(new Date().getTimezoneOffset());

// Current time
console.log(new Date().toString());

Check Flight Data Timezone

// In Network tab, look at flight API response
// Times might include timezone info like:
// "scheduledTime": "2024-01-15T14:30:00+01:00"
// The +01:00 indicates the timezone

Still Wrong Times?
