java 时间戳和PHP时间戳 的转换 原文地址:http://www.myexception.cn/php/1032678.html 总结一下java 时间戳和PHP时间戳 的转换问题: 由于精度不同,导致长度不一致,直接转换错误。 JAVA时间戳长度是13位,如:1294890876859 PHP时间戳长度是10位, 如:1294890859 主要最后三位的不同,JAVA时间戳在PHP中使用,去掉后三位,如:1294890876859-> 1294890876 结果:2011-01-13 11:54:36 echo date(‘Y-m-d H:i:s’,’1294890876′); PHP时间戳在JAVA中使用,最后加三位,用000补充,如:1294890859->1294890859000 结果:2011-01-13 11:54:19 SimpleDateFormat df = new SimpleDateFormat(“yyyy-MM-dd HH:mm:ss”); String dateTime = df.format(1294890859000L); System.out.println(df);
