Bug - Tests - Timestamp tests keeps failing because of wrong format

[Dominik-Petrik]

Describe the problem
When running yarn test Timestamp tests keep failing for some non-US located contributors, since date time format is not fixed.

Is this issue blocking you?
If this is blocking you adding LC_ALL=en_US.UTF8 argument to test script in package.json solves the problem
