This is very strange.
If you check assets/scripts/wallets-faucet.js you will find that in cases where the remaining time is more than 1 hour, the time is now displayed as human-readable text. Additionally, I have tested this extensively.
My first thought was that the old JavaScript code is still running on your browser, but I have made sure to attach a version number to the wp_enqueue_script() call so this is not very likely. It might be worth clearing your cache anyway just to make sure.
kind regards
