Closed time-loop in spacetime

" IF PROPER TIME IS MONOTONIC STRICTLY INCREASING SINGLE VALUED REAL PARAMETER, NO CLOSED TIME LOOP CAN EXIST IN SPACETIME" PROPER TIME[IF REAL] CAN BE CONSIDERED TO BE AN "ORDERED FIELD" LEADING TO THE IDEA OF 'NON EXISTENCE' OF CLOSED TIME-LOOP IN SPACETIME.

if proper time is monotonically increasing single valued real parameter,no closed time-loop can exist in spacetime?
