Bug with Materials

Hello guys

first of all thanks for your efforts , but to be honest it is not enough , like the last bug you replied to it was a month ago , the slack URL is not working , half of the learning lessons in the website are incomplete or broken , there is no way of any kind of communication with you guys , how the hell you want to people to use famous !!

anyway i tried to add materials to my webGL content , but i faced an error related to the time line
var time = Material.time();

compile error: ERROR: 0:98: 'time' : undeclared identifier
