Time difference in C++
Hi guys, Does anyone know how to calculate time difference in C++ in miliseconds? I used difftime (time.h) but it's not enough precision for what I'm trying to measure. Thanks, in advance. Alejo ...

How to decompose unix time in C
This seems like something no one should ever have to do, but I'm working on a kernel module for an embedded system (OpenWRT) in which it seems that time.h does include the timespec and time_t types, and the clock_gettime and gmtime functions, but does not include localtime, ctime, time, or, critically, the tm type.

I'm assuming the numbers in the square brackets are the ranges possible for each respective member of the structure. So why is there 0~61 possible range for seconds? Were there 62 second...
Ubuntu Linux C++ error: undefined reference to 'clock_gettime' and 'clock_settime'
I am pretty new to Ubuntu, but I can't seem to get this to work. It works fine on my school computers and I don't know what I am not doing. I have checked usr/include and time.h is there just fine. Here is the code: #include <iostream> #include <time.h> using namespace std; int main() { timespec time1, time2; int temp; c...
