如何将时代转换为JAVA中的mySQL时间戳

Question

如何在mySQLtimestamp中获取mySQL时间戳格式？

long epochNow = System.currentTimeMillis()/1000; 
long epochWeek = 604800; 
long date7daysAgo = epochNo2013 w - epochWeek; 
String mySQLtimestamp = /* 2013-09-23:50:00 */

为什么不一直使用正常的Date？

Calendar cal = Calendar.getInstance(); 
cal.add(Calendar.DAY_OF_MONTH, -7); 
SimpleDateFormat formatter = new SimpleDateFormat("yyyy-MM-dd HH:mm:ss"); 
String output = formatter.format(cal.getTime());
