Method 1: Current Timestamps in Milliseconds from the Unix Epoch using chrono Library We can get the elapsed time since the epoch by std::chrono since C++11. The goal is to use chrono::system_clock::now() to retrieve the current system time. Then call the time_since_epoch() method to...
The time64() function determines the current calendar time, in seconds. Note: Calendar time is the number of seconds that have elapsed since EPOCH, which is 00:00:00, January 1, 1970 Universal Coordinate Time (UTC). Return Value The time64() function returns the current calendar time. ...
