格式時間轉(zhuǎn)UTC時間
最近項目里面 用到一個 把給定格式的時間轉(zhuǎn)換成UTC時間 ,話不多說!直接上代碼.
public void dateChange() throws ParseException {
String str="2010-5-27 12:10:12";
SimpleDateFormat sdf= new SimpleDateFormat("yyyy-MM-dd HH:mm:ss");
Date date =sdf.parse(str);
Calendar calendar = Calendar.getInstance();
calendar.setTime(date);
int zoneOffset = calendar.get(Calendar.ZONE_OFFSET);
int dstOffset = calendar.get(Calendar.DST_OFFSET);
calendar.add(Calendar.MILLISECOND, -(zoneOffset + dstOffset));
long timeInMillis = calendar.getTimeInMillis();
SimpleDateFormat df = new SimpleDateFormat("yyyy-MM-dd'T'HH:mm:ss.SSS'Z'");
System.out.println(df.format(timeInMillis));
}
