Been using this code for awhile now and one of the things i noticed is some of the time on people's device are off by a few seconds that can mess with the token on their end. Is it possible to modify this code so that its checks what they enter, fail it and then run the code again but this time run the code with "time-30 seconds" so that it basically approves the token that is valid right now and the token that was valid before.
