If space can be viewed as being infinite, then time may be viewed as being infinite, also, as the speed of information transfer ("light") is finite. (Pease re-read Professor Griffiths' last sentence in the above.)
In any case, models of infinite cosmologies (both of time and space) exist, and have found their way into The Physical Review Letters, a peer-reviewed journal of the APS.
I am not a physicist, but have read Professor Griffiths' undergraduate QM texts (both the 2nd and 3rd editions) and have found his proof helpful in understanding Professor Sean Carroll's (who is a physicist) Quatum Eternity Theorem.
That's all I have ever claimed. (And, it's a free country, and I can post what I like subject to the moderators approval/disaprroval.)
