java public class CurrentTimeMillisExample { public static void main(String[] args) { // 获取当前时间的毫秒数 long currentTimeMillis = System.currentTimeMillis(); // 打印当前时间的毫秒数 System.out.println("Current time in milliseconds: " + currentTimeMillis); // 示例:计算程序运行时间 long...
Returns: the difference, measured in milliseconds, between the current time and midnight, January 1, 1970 UTC. 可见这个方法获取的是当前系统时间与1970.1.1 0:0:0的时间差的毫秒数,最后一句提到这个时间是UTC的,所以在C#中应该如此实现: longt = (long)(DateTime.UtcNow.Subtract(newDateTime(1970,1,1)...
JavaScript: Use Date.now() to get the current time in milliseconds. Python: Use time.time() * 1000 for millisecond precision. Java: System.currentTimeMillis() provides millisecond accuracy. This quick retrieval of time in milliseconds enables developers to accurately monitor and timestamp system ...
