Well, no!

I think, that time is local and depending on scale.

We as human beings have a certain 'natural' scale, because we relate 
length to a usual step and time to a usual day.

But what if you have lived your entire life in a different world, where 
everything is a hundred times larger and a hundred times slower?

Wouldn't you regard that scale as 'natural' as well?
