Problem is nobody has ever heard of Mark Thakkar. Why
should somebody invest time in reading Mark Thakkar?
What is your motivational speak for him, except your

own confusion as usual? Is he famous for something? So 
I don't know exactly what you should read for temporal
logic. Maybe this here:

Papers on time and tense
by Prior, A. N. (Arthur N.), 1914-1969
https://archive.org/details/papersontimetens0000prio_k3r9/page/n5/mode/2up

It has nice chapters like FUGITIVE TRUTH, etc.. etc..

LoL
