Time Measurement Unit in CPLEX

Question

In IBM ILOG CPLEX model I use "MyCplex.getCplexTime()" for measuring the time but it gives output as "time:2338551.031". I couldn`t figure out the unit of it. Is there any code to get time in seconds?

Answer 1

let me quote CPLEX documentation:

To measure time spent between a starting point and ending point of an operation, take the time stamp at the starting point; take the time stamp at the ending point; subtract the starting time stamp from the ending time stamp to get elapsed time in seconds.

This computation measures either wall clock time (also known as real time) or CPU time, depending on the setting of the clock type parameter ClockType.

The absolute value of the time stamp is not meaningful.
