This is C source code written in Gcc platform (Linux, Ubuntu) that finds the compilation time of any other source code (e.g. C, C++, Java & others). It also finds the execution time of any command of Ubuntu in three time units: nanosecond, microsecond and millisecond.
Note: If you want to find the compilation time of a piece of Java source code using this C source code, the Java compiler must be installed in the machine.
