How to Get the Date and Time

So I've seen someone lately that wanted to get the date and time of the server, and here I have it! First, you're going to need to define some variables.

Code:java

Date now = new Date();
SimpleDateFormat format = new SimpleDateFormat("dd-MM-yyyy HH:mm:ss");

You can edit that however you want, so for example, you could have MM/dd/yyyy to have it print 10/23/2012 instead of 23-10-2012.

After that, you're going to actually want to get the date and print it. In the past, I've used it to... display the date and time... I do that like this:

Code:java

System.out.println("[" + format.format(now) + "] " + message);

The first format is the variable that you set earlier, then the second format is java's DateFormat. The message that prints something is along the lines of this:

Code:

[11-10-2012 15:44:11] Message

REMEMBER: This prints the time of the computer that is running the minecraft server. So if you were to have a command like /time and send the time to a player, it wouldn't print the time of the player's computer, it would print the time of the computer that is running the server.

 

Thanks for clarifying that, I think this will help a lot of people, not necessarily while making Bukkit plugins!

I agree

 

This is great. Could you give an example of how I would get the date saved in a file, and check how long ago it was.

 

By using a java filewriter, and then using some method to get the time from the date you put in there. I'm not making the code for you ._.

 

Lol. That's what i don't know how to do, i have saved the time and date to a file but dont know what next. Do i get it from the file as a string, and how do i compare it to todays date. I want to test if the date in the file was more than 30 days ago. I'm not expecting you to write it for me but any hints/tips would be appreciated.

 

Split the string with whatever you used to split up the month/date/year in the SimpleDateFormat you created, and compare those results with the results that you get with the date today.

 

You know, you could've just googled this

Um, now.. I'm not sure if I'm doing something wrong.. or if this plugin is drunk...

But when I had it grab the date.. I got a result of "01-01-1970"...

Offtopic, but dang, that was really close to 1969

EDIT by Moderator: merged posts, please use the edit button instead of double posting.

 

Not sure why you got that result. I remember reading somewhere that if you get System.currentTimeMillis() it will return the amount of milliseconds since 01.01.70

Show us your code.

 

If you want to find the difference in two times, it's easier to store System.currentTimeMillis() to a file, then compare it to the current time, whenever you're checking.

Code:

                Date now = new Date(0);
                SimpleDateFormat format = new SimpleDateFormat("dd-mm-yyyy");
                nameconfig.set("Join-Date", format.format(now));
                nameconfig.save(name);

Have to use "(0)" for Date, other wise it brings a NullPointerException.

 

Whats the 0 for?

Date now = new Date(0);
Date now = new Date();

Like I said, just having Date() gives me a EventException.

Code:

Check your imports, you want java.util not java.sql

Was just a good guess.
