How to extract time and date using regular expressions?

Question

JavaScript

I get the time and date in the following format: 2017-03-03T21:07:24.072Z.
How to use regular expressions to write date and time into two variables?
Or is it possible in some other way?
Sending to the server: ..... new Date();
I receive and process: ..... data.toJSON();
And I get: 2017-03-03T21:07:24.072Z
