Description

The code is as follows ：

Calendar cale = Calendar.getInstance();
System.out.println("Old time is " + DateFormatUtils.format(cale, "yyyyMMddHHmmss"));
cale.setTimeZone(TimeZone.getTimeZone("JST"));
System.out.println("New time is " + DateFormatUtils.format(cale, "yyyyMMddHHmmss"));

 

The results of commons-lang3 3.4：
