C++ Keeping track of how many seconds has passed since start of program

Question

I am writing a program that will be used on a Solaris machine. I need a way of keeping track of how many seconds has passed since the start of the program. I\'m talking very sim

Answer 1

A very simple method:

#include 
time_t start = time(0);

double seconds_since_start = difftime( time(0), start);

The main drawback to this is that you have to poll for the updates. You'll need platform support or some other lib/framework to do this on an event basis.
