..and you would insert that on line 175.+ 'on ' + moment(new Date(abbr.dataset.utime * 1000)).format('l \\at LTS')
Edit the script according to as shown below or it will not work since the script uses an unapproved Javascript library for displaying the times, you'll need to remove the space between
// @ require for moment.js
in the code.
// @require http://momentjs.com/downloads/moment.min.js
// @require https://momentjs.com/downloads/moment-with-locales.min.js
