Why TimeZone BUG 1 hour

View Line:
System.out.println("sdf: " + sdf.format(hours));//ERROR HERE
System.out.println("sdf2: " + sdf2.format(hours)); //BUT HERE, NO PROBLEM

Code: (Computer Hours from Brazil)

Code:

        SimpleDateFormat sdf = new SimpleDateFormat("HH-mm");
        SimpleDateFormat sdf2 = new SimpleDateFormat("HH-mm");
        TimeZone tz = TimeZone.getTimeZone("America/New_York");
        sdf.setTimeZone(tz);
        Date hoursCurrently = new Date(System.currentTimeMillis());
    
        Date hours = sdf2.parse(sdf2.format(new Date(System.currentTimeMillis())));

        System.out.println("sdf:  " + sdf.format(hoursCurrently));
        System.out.println("sdf:  " + sdf.format(hours));//ERROR HERE
        System.out.println("sdf2:  " + sdf2.format(hours)); //BUT HERE, NO PROBLEM
        System.out.println("sdf2:  " + sdf2.format(hoursCurrently));

Out:
sdf: 14-03
sdf: 13-03
sdf2: 15-03
sdf2: 15-03

What is the problem?
sdf2 has another timezone than sdf (if you don't live in New York). Why should they print out the same?
What should they even print out?

 

@I Al Istannen When create a date from sdf2.parse(); and after format this date, this date reduce 1 hour. But when create a date direct with new Date() and after format, he works.
I want know because it happens

Output for me:

Code:

sdf:  11-31
sdf:  11-31
sdf2:  17-31
sdf2:  17-31

What you would expect. Strange.
