Java code for getting current time [duplicate]

Answer 1

Both

new java.util.Date()

and

System.currentTimeMillis()

will give you current system time.

Answer 2

try this to get the current date.You can also get current hour, minutes and seconds by using getters :

new Date(System.currentTimeMillis()).get....()

Answer 3

Just to inform for furthers developers, and thankfully to Basil Bourque, I just wanna add my stone to this topic.

If you want simply get the HH:MM:SS format then do this:

LocalTime hour = ZonedDateTime.now().toLocalTime().truncatedTo(ChronoUnit.SECONDS);

Cheers.

P.S.: This will work only at least with Java 8 !

Answer 4

try this:

final String currentTime    = String.valueOf(System.currentTimeMillis());

Answer 5

new Date().getTime() is bugged.

    Date date = new Date();
    System.out.println(date);
    System.out.println(date.getHours() + ":" + date.getMinutes() + ":" + date.getSeconds());
    long t1 = date.getTime();
    System.out.println((t1 / 1000 / 60 / 60) % 24 + ":" + (t1 / 1000 / 60) % 60 + ":" + (t1 / 1000) % 60);
    long t2 = System.currentTimeMillis();
    System.out.println((t2 / 1000 / 60 / 60) % 24 + ":" + (t2 / 1000 / 60) % 60 + ":" + (t2 / 1000) % 60);

It returns me the wrong time millis. System.currentTimeMillis() too. Since I ask the Date instance to tell me the corresponding time millis it must return the matching ones not others from a different time zone. Funny how deprecated methods are the only ones which return correct values.

Answer 6

To get system time use Calendar.getInstance().getTime()

And you should get the new instance of Calendar each time to have current time.

To change system time from java code you can use a command line
