By forking the repo and changing versions to 14 in projects/mat-timepicker/package.json it managed to install, but fails to compile with many errors.

Sorry but I've just created a new project using:

Angular CLI: 14.1.3
Node: 14.15.5
Package Manager: yarn 1.22.19
OS: darwin x64

steps:

ng new test
cd test
ng add @angular/material
yarn add mat-datepicker@latest
ng s

inside the app.module I've added the MatTimepickerModule

and inside the app.component.html

<input matTimepicker>

It compiled without errors, warnings and it works like a charm.

I think your issue is caused by your environment because as you see you get ERESOLVE error from NPM which means that the package cannot be resolved and one thing to check out is this npm ERR! While resolving: timepicker-test@0.0.0. I have no idea what timepicker-test@0.0.0 is, so it must be something local to your env.

Good luck!
