             Summary: don’t need 
cal.setTimeInMillis(System.currentTimeMillis()) after Calendar.getInstance()
                 Key: ROCKETMQ-269
                 URL: https://issues.apache.org/jira/browse/ROCKETMQ-269
             Project: Apache RocketMQ
          Issue Type: Improvement

            Reporter: Mark Yang
            Assignee: Jixiang Jin


don’t need cal.setTimeInMillis(System.currentTimeMillis()) after 
Calendar.getInstance()


In JDK’s source code, innermost constructor for Calendar.getInstance() is:

public GregorianCalendar(TimeZone zone, Locale aLocale) {    
 super(zone, aLocale);     gdate = (BaseCalendar.Date) 
gcal.newCalendarDate(zone);     
 setTimeInMillis(System.currentTimeMillis()); 
}
