Scheduled Flight Times Discrepency

FlightAware AeroAPI
1

I hope some one can help. I am seeing a discrepency between scheduled times when using the flight api with ident . the Flight Number is QTR631/QR631 the Scheduled depart should be 02:00am however this has a completely different time ? below is the results from the flight api lookup

At first I thought it might be UTC to Local timezone issue but that would still be 2 hours out. Obviously Flight aware has the correct data but perhaps im using the value incorrectly.

Hope you can help

Cheers

Dave

The trailing “Z” in the ISO8601 timestamps indicates that the timestamps are represented in UTC/Zulu timezone.

When converting to localtime, be sure to use the timezone of the origin airport for off and out times, and the timezone of the destination airport for the on and in times.

The 25th Zulu/UTC time would equate to the 26th local time meaning the flight that you are looking at with a 25th 2300Z scheduled departure time would actually be the 26th at 0400 local. For the flight on the 25th local, you would need to find the flight on the 24th Zulu time.
See below for the snippet of the flight you should be using.
