![Java: to Get Current India Time [Duplicate]](https://docuprint.cloud68.co/uploads/java-to-get-current-india-time-duplicate_1200.jpg)
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

The Date API has been superseded by a new JodaTime-like API in Java 8.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);
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.
