Why can i show timestamp the correct date on development environment and on quality environment only show timestamp default data(01-01-1970)?

I have a problem with timestamp.
I’m working in two different environments, quality and development.

And I want to show the date modified file with this format DD-MM-YYYY.

In development environment, its working fine. But when I make the deploy to quality, it shows the timestamp default date (01-01-1970).

Why this is happen?

thanks!
