Provide the watchtime per user on a single event / stream on Twitch using StreamElements. These are very simple PHP scripts and easy to use. Feel free to edit the code for your needs.

• Download all files and upload them to any webserver providing PHP.
• Edit the 'cron.php' and change the URL. It has to point to your 'subathon.php'.
• Edit the 'subathon.php' and change the texts in the very last line as you want.
• Create a cron job on your webserver for opening the 'cron.php' every few minutes. The time between every execution must be < 10 minutes.
• Add a new chat command in your StreamElements-panel using the following code:

${urlfetch http://www.urltoyour.php/subathon.php?action=get&channel=your_channel&user=${user.name}}
