What is the difference between the current timestamp in GMT time zone and the current timestamp in your local time zone?

This is an example of a question that I found in a test verification of the ZEND php certificate, the correct answer to this question: “There is no difference between the current time in any time zone - the current time is an absolute point in time!” This answer is very strange and confusing. I don’t understand why this answer is correct, in fact I think it depends on the number of hours between the local time zone and GMT. Can anyone help with this?

The response says that all over the world this is only one particular point in time. We have different ways of representing this moment in time in different time zones, but the actual specific point in time on Earth is everywhere the same as here.
