After some extensive searching on their official website, I've found out that no support files could be downloaded, and this is primarily due to the fact that their product is not available for general public and it's meant for businesses from that domain of work.

Look through the Help database of the software to see if you can change the flight times on scheduled routes to Zulu Time.
Get in touch with the developers of the software to see exactly if that's even possible: https://tflite.com/support-training/request-a-demo/
