My iOS devices are defaulting to UKand displaying EU dates

My iOS devices are defaulting to UKand displaying EU dates. I installed the same build on a physical device and the dates display US because that is my device setting. What could be the reason?

Hello Dipen,
LambdaTest has data centers US, Europe and India and depending on the user’s location, the nearest data center is allocated for the test. Looks like, you got EU data center due to which the devices are in EU date format.
