Java: to Get Current India Time [Duplicate]

Question

I am not able to get current india time.

I want to get current time for india, i updated my system clock after 5 minute then current time, so my system clock is running 5 minute earlier than actual india time but i want to get standard time for india.

current time is 11:05:06 and machine time is 11:10:06

public class TestDate {

    public static void main(String[] args) {
        SimpleDateFormat sd = new SimpleDateFormat("yyyy.MM.dd G 'at' HH:mm:ss z");
        Date date = new Date();
        sd.setTimeZone(TimeZone.getTimeZone("IST"));
        System.out.println(sd.format(date));
    }
}

output : 2019.02.12 AD at 11:10:06 IST
expected : 2019.02.12 AD at 11:05:06 IST

but i am getting wrong output , so please suggest

Accepted Answer

The Date API has been superseded by a new JodaTime-like API in Java 8.
Use a ZonedDateTime object.

final ZonedDateTime now = ZonedDateTime.now(ZoneId.of("Asia/Kolkata"));

This will give you the output 2019-02-11T14:49:28.625+05:30[Asia/Kolkata]

To format a Temporal use a DateTimeFormatter.

DateTimeFormatter.ofPattern("yyyy-MM-dd HH:mm:ss")
                 .format(now);

Answer 2

UTC+05:30

This is not a timezone, it's just an offset. You need to use valid timezone in order to print the date in that timezone, e.g.: Asia/Kolkata.

Following should work:

public static void main(String[] args) throws JsonParseException, JsonMappingException, IOException {
    SimpleDateFormat gmtDateFormat = new SimpleDateFormat("yyyy-MM-dd HH:mm:ss");
    gmtDateFormat.setTimeZone(TimeZone.getTimeZone("Asia/Kolkata"));
    //Current Date Time in GMT
    System.out.println("Current Date and Time in UTC time zone: " + gmtDateFormat.format(new Date()));
}

Also, Asia/Kolkata timezone is not always UTC+05:30, it depends on daylight saving. So, we should rather use timezone by name than offset.
