Creating a USB Installer for El Capitan or High Sierra

Creating USB installers for older versions of Mac OS X can be tricky, so I decided to put together a more detailed walkthrough. High Sierra is similar, but you actually want to use a different date timestamp!
El Capitan Create USB Command:
sudo /Applications/Install\ OS\ X\ El\ Capitan.app/Contents/Resources/createinstallmedia --volume /Volumes/el-cap --applicationpath /Applications/Install\ OS\ X\ El\ Capitan.app
El Capitan Date Change Command:
Date -u 0923020415
High Sierra Date Change Command:
date -u 0818025919
