Epoch in AngelScript
A common requirement in programs is getting the number of seconds, milliseconds, or nanoseconds since the Unix epoch. Here’s how to do it in AngelScript.
#include <chrono>
#include <iostream>
#include <ctime>
void main()
{
// Use std::chrono::system_clock::now() to get the current time
auto now = std::chrono::system_clock::now();
std::cout << now.time_since_epoch().count() << std::endl;
// Get elapsed time since the Unix epoch in seconds, milliseconds, or nanoseconds
auto seconds = std::chrono::duration_cast<std::chrono::seconds>(now.time_since_epoch()).count();
auto milliseconds = std::chrono::duration_cast<std::chrono::milliseconds>(now.time_since_epoch()).count();
auto nanoseconds = std::chrono::duration_cast<std::chrono::nanoseconds>(now.time_since_epoch()).count();
std::cout << seconds << std::endl;
std::cout << milliseconds << std::endl;
std::cout << nanoseconds << std::endl;
// Convert integer seconds or nanoseconds since the epoch into the corresponding time
auto time_point = std::chrono::system_clock::from_time_t(seconds);
std::time_t tt = std::chrono::system_clock::to_time_t(time_point);
std::cout << std::ctime(&tt);
auto time_point_nano = std::chrono::system_clock::time_point(std::chrono::nanoseconds(nanoseconds));
tt = std::chrono::system_clock::to_time_t(time_point_nano);
std::cout << std::ctime(&tt);
}In this AngelScript code, we use the <chrono> library to work with time. The std::chrono::system_clock::now() function is used to get the current time.
We then use duration_cast to convert the time to seconds, milliseconds, and nanoseconds since the Unix epoch.
To convert integer seconds or nanoseconds back to a time point, we use std::chrono::system_clock::from_time_t() and std::chrono::system_clock::time_point() respectively.
When you run this program, you’ll see output similar to this:
1685123456789012345
1685123456
1685123456789
1685123456789012345
Fri May 26 12:34:56 2023
Fri May 26 12:34:56 2023The exact numbers will depend on when you run the program.
Next, we’ll look at another time-related task: time parsing and formatting.
