PhpStorm becomes unresponsive when manually changing time & date on Mac

After changing date & time in MacOS settings, PhpStorm's main code panel becomes unresponsive -- you cannot set the cursor, type any code or use key navigation there. However key navigation in the left "Project Files" panel still works.

The code panel becomes responsive back again if you invalidate caches and restart PhpStorm.

If you're debugging a project with the use of JavaScript time & date functionality, you might often want to change date and time on your computer manually. In that case, working in PhpStomr becomes a hassle as you have to constantly restart it.
