[java] How to get the current date and time of your timezone in Java?

I have my app hosted in a London Server. I am in Madrid, Spain. So the timezone is -2 hours.

How can I obtain the current date / time with my time zone.

Date curr_date = new Date(System.currentTimeMillis());

e.g.

Date curr_date = new Date(System.currentTimeMillis("MAD_TIMEZONE"));

With Joda-Time

DateTimeZone zone = DateTimeZone.forID("Europe/Madrid");
DateTime dt = new DateTime(zone);
int day = dt.getDayOfMonth();
int year = dt.getYear();
int month = dt.getMonthOfYear();
int hours = dt.getHourOfDay();
int minutes = dt.getMinuteOfHour();

As Jon Skeet already said, java.util.Date does not have a time zone. A Date object represents a number of milliseconds since January 1, 1970, 12:00 AM, UTC. It does not contain time zone information.

When you format a Date object into a string, for example by using SimpleDateFormat, then you can set the time zone on the DateFormat object to let it know in which time zone you want to display the date and time:

Date date = new Date();
DateFormat df = new SimpleDateFormat("yyyy-MM-dd HH:mm:ss");

// Use Madrid's time zone to format the date in
df.setTimeZone(TimeZone.getTimeZone("Europe/Madrid"));

System.out.println("Date and time in Madrid: " + df.format(date));

If you want the local time zone of the computer that your program is running on, use:

df.setTimeZone(TimeZone.getDefault());

I couldn't get it to work using Calendar. You have to use DateFormat

//Wednesday, July 20, 2011 3:54:44 PM PDT
DateFormat df = DateFormat.getDateTimeInstance(DateFormat.FULL, DateFormat.FULL);
df.setTimeZone(TimeZone.getTimeZone("PST"));
final String dateTimeString = df.format(new Date());

//Wednesday, July 20, 2011
df = DateFormat.getDateInstance(DateFormat.FULL);
df.setTimeZone(TimeZone.getTimeZone("PST"));
final String dateString = df.format(new Date());

//3:54:44 PM PDT
df = DateFormat.getTimeInstance(DateFormat.FULL);
df.setTimeZone(Timezone.getTimeZone("PST"));
final String timeString = df.format(new Date());

DateFormat df = DateFormat.getDateTimeInstance(DateFormat.FULL, DateFormat.FULL);
df.setTimeZone(TimeZone.getTimeZone("PST"));
final String dateTimeString = df.format(new Date());

Check this may be helpful. Works fine for me. Code also covered daylight savings

    TimeZone tz = TimeZone.getTimeZone("Asia/Shanghai");
    Calendar cal = Calendar.getInstance();      
    // If needed in hours rather than milliseconds
    int LocalOffSethrs = (int) ((cal.getTimeZone().getRawOffset()) *(2.77777778 /10000000));        
    int ChinaOffSethrs = (int) ((tz.getRawOffset()) *(2.77777778 /10000000));       
    int dts = cal.getTimeZone().getDSTSavings();
    System.out.println("Local Time Zone : " + cal.getTimeZone().getDisplayName());
    System.out.println("Local Day Light Time Saving : " + dts);
    System.out.println("China Time : " + tz.getRawOffset());
    System.out.println("Local Offset Time from GMT: " + LocalOffSethrs);
    System.out.println("China Offset Time from GMT: " + ChinaOffSethrs);    
    // Adjust to GMT
    cal.add(Calendar.MILLISECOND,-(cal.getTimeZone().getRawOffset()));  
    // Adjust to Daylight Savings
    cal.add(Calendar.MILLISECOND, - cal.getTimeZone().getDSTSavings());
    // Adjust to Offset
    cal.add(Calendar.MILLISECOND, tz.getRawOffset());       
    Date dt = new Date(cal.getTimeInMillis());              
    System.out.println("After adjusting offset Acctual China Time :" + dt); 

You would use JodaTime for that. Java.util.Date is very limited regarding TimeZone.

Here are some steps for finding Time for your zone:

Date now = new Date();

 DateFormat df = new SimpleDateFormat("MM/dd/yyyy HH:mm:ss");  
 df.setTimeZone(TimeZone.getTimeZone("Europe/London"));  

 System.out.println("timeZone.......-->>>>>>"+df.format(now));  

Date in 24 hrs format

Output:14/02/2020 19:56:49 PM

 Date date = new Date();
 DateFormat dateFormat = new SimpleDateFormat("dd/MM/yyyy HH:mm:ss aa");
 dateFormat.setTimeZone(TimeZone.getTimeZone("Europe/London"));
 System.out.println("date is: "+dateFormat.format(date));

Date in 12 hrs format

Output:14/02/2020 07:57:11 PM

 Date date = new Date();`enter code here`
 DateFormat dateFormat = new SimpleDateFormat("dd/MM/yyyy hh:mm:ss aa");
 dateFormat.setTimeZone(TimeZone.getTimeZone("Europe/London"));
 System.out.println("date is: "+dateFormat.format(date));

using Calendar is simple:

Calendar calendar = Calendar.getInstance(TimeZone.getTimeZone("Europe/Madrid"));
Date currentDate = calendar.getTime();

To get date and time of your zone.

Date date = new Date();
DateFormat df = new SimpleDateFormat("MM/dd/YYYY HH:mm a");
df.setTimeZone(TimeZone.getDefault());
df.format(date);

With the java.time classes built into Java 8 and later:

public static void main(String[] args) {
        LocalDateTime localNow = LocalDateTime.now(TimeZone.getTimeZone("Europe/Madrid").toZoneId());
        System.out.println(localNow);
        // Prints current time of given zone without zone information : 2016-04-28T15:41:17.611
        ZonedDateTime zoneNow = ZonedDateTime.now(TimeZone.getTimeZone("Europe/Madrid").toZoneId());
        System.out.println(zoneNow);
        // Prints current time of given zone with zone information : 2016-04-28T15:41:17.627+02:00[Europe/Madrid]
    }
