Dates are changing in the server since there is a common use in SimpleDateFormat which is not thread safe

We need to synchronize it, use Thread Local or change to Java 8 DateTimeFormatter

DateTimeFormatter formatter = DateTimeFormatter.ofPattern("yyyy-MM-dd");
String str = new java.util.Date().toInstant()
                                 .atZone(ZoneId.systemDefault())
                                 .format(formatter);
