在Java里面,时间戳常用System.currentTimeMillis(),因为它可以方便地与Date/Calendar进行转 换,System.nanoTime到不是怎么常用(至少我没怎么用过)。刚才在学习Java的线程池中的 ScheduledThreadPoolExecutor时,看到里面很多地方都用到了它,于是好奇地看了下API。
Using Java as an example, System.currentTimeMillis() returns just that, a UNIX timestamp in milliseconds - UNIX timestamps will often be measured in seconds as well (but System.currentTimeMillis() will always be in milliseconds). Following is a table that unifies these concepts: A human ...
