how to get current time of device in j2me?

[manojkumar.m]

Hello friends,

I want to know the current time(hh:mm:ss) of device by writing simple midlet. I dont know how to proceed. could you please tell me how to achieve this?

[jappit]

This code should work for you:

Date d = new Date();
		
Calendar c = Calendar.getInstance();
		
c.setTime(d);
		
String time = c.get(Calendar.HOUR_OF_DAY) + ":" + 
	c.get(Calendar.MINUTE) + ":" + 
	c.get(Calendar.SECOND);

If you want 12h-based hour, you can get it with c.get(Calendar.HOUR) and check if is AM/PM with the Calendar.AM_PM property.

Hi jappit,
thanks for your reply, but when I executed the application as you suggestd, its working fine on emulator, but when istalled on Nokia E61i and Nokia 6300, it is not installing and showing an error message : application not compatible with this phone.
my code is :

public class DateAndTime extends MIDlet implements CommandListener
{
Display disp;

Form form = new Form("Data and Time");
Command start = new Command("start", Command.SCREEN, 1);
Command exit = new Command("Exit", Command.EXIT, 0);
Date d ;
Calendar c = Calendar.getInstance();
String time;
public void startApp()
{
form.append("TIME IS : ");
form.addCommand(start);
form.addCommand(exit);
form.setCommandListener(this);
disp = Display.getDisplay(this);
disp.setCurrent(form);
}

public void pauseApp()
{
}

public void destroyApp(boolean uncond)
{
}

public void commandAction(Command cmd, Displayable s)
{
if (cmd == exit)
{
notifyDestroyed();
}
else
if (cmd == start)
{
d = new Date();
c.setTime(d);
time = c.get(Calendar.HOUR_OF_DAY) + ":" +c.get(Calendar.MINUTE) + ":" + c.get(Calendar.SECOND);
form.append("" + time);
form.append("\n");
}
}
}

what is the problem?

Which CLDC and MIDP versions are you using? Also, are you using any non-standard APIs (even if it seems you're not from your code)?

CLDC 1.1 and MIDP 2.1
I am using only standard APIs.

[jappit]

Both Nokia E61i and 6300 support MIDP 2.0, not MIDP 2.1, so you should change that setting. To be sure about phone specifications and supported APIs, always check here:

Though I changed the emulator settings to MIDP 2.0, it still shows the same error message.

Thankyou jappit,
now i changed the emulator settings as suggested you.
now it is installed on my devices.
once again thanks for quick response.

One more doubt, when I started the midlet on my mobile, the current time is 15:59:1.

and the midlet shows the current time as 15:29:01.

I dont know why there is a difference of 30 minutes.

what might be the problem? any suggestions?

[jappit]

Mumble... do both phones give you the wrong time? Or one only (which one)?
