您可以使用以下功能
private Date shiftTimeZone(Date date, TimeZone sourceTimeZone, TimeZone targetTimeZone) {
Calendar sourceCalendar = Calendar.getInstance();
sourceCalendar.setTime(date);
sourceCalendar.setTimeZone(sourceTimeZone);
Calendar targetCalendar = Calendar.getInstance();
for (int field : new int[] {Calendar.YEAR, Calendar.MONTH, Calendar.DAY_OF_MONTH, Calendar.HOUR, Calendar.MINUTE, Calendar.SECOND, Calendar.MILLISECOND}) {
targetCalendar.set(field, sourceCalendar.get(field));
}
targetCalendar.setTimeZone(targetTimeZone);
System.out.println("........"+targetCalendar.getTimeZone());
return targetCalendar.getTime();
}
用法:
Date date= new Date();
SimpleDateFormat sf = new SimpleDateFormat("dd-MM-yyyy HH:mm:ss");
sf.format(date);
TimeZone tz = TimeZone.getTimeZone("GMT") OR TimeZone tz = sf.getTimeZone();
TimeZone tz1 = TimeZone.getTimeZone("EST");
Date c= shiftTimeZone( date,tz,tz1);
System.out.println("Format : " + sf.format(c));
输出 sun.util.calendar.ZoneInfo[id="EST",offset=-18000000,dstSavings=0,useDaylight=false,transitions=0,lastRule=null]
