How modify a cookie in the browser

[592]

Hello,

A website that sets up a queue
It seems impossible to skip the queue. But when I have my ticket then I can access the website and I am explused after about 15 minutes.
It is a cookie that is installed in the browser
 
I'm not a specialist, but is it possible to modify this cookie in the browser to delete the timer, and remain connected to the website?
 
Thank you
