Reporting this as a bug, hence I feel this wasn't your intention with the new timer system.
If the video is unable to load, it shows how the timer system can be tricked into giving additional time for free, and how the timer can be staled/how the new AFK mode to the timer can be turned off without committing any plays.

Thats not really a bug , and it also doesnt give infinite time, as there is a max amount of time that can be added each turn, so once the cap is hit, no more time can be gained.
This was one of the main reasons the timer was reworked as you used to be able to gain an infinite amount of time with a similar method
