Current behavior

Currently you have to specify a timezone and/or locale for every instance of the Date pipe you have. Otherwise, according to the docs, "If not specified, the local system timezone of the end-user's browser will be used.".

Expected behavior

It would be nice to have a way to set the default values for these fields for the entire app, rather than having to add these to every instance of the date pipe.

What is the motivation / use case for changing the behavior?

If you have more than a handful of date pipes throughout your app it would good to have a single place to change the timezone and locale rather than having to change all instances each time you want to make a change. In my current application I have hundreds of date pipes scattered throughout the app.

Environment

Angular version: 5.0.0-beta.6
