How can I get the current date and time in UTC or GMT in Java?

Answer 1

Converting Current DateTime in UTC:

DateTimeFormatter formatter = DateTimeFormat.forPattern("yyyy-MM-dd'T'HH:mm:ss.SSS'Z'");

DateTimeZone dateTimeZone = DateTimeZone.getDefault(); //Default Time Zone

DateTime currDateTime = new DateTime(); //Current DateTime

long utcTime = dateTimeZone.convertLocalToUTC(currDateTime .getMillis(), false);

String currTime = formatter.print(utcTime); //UTC time converted to string from long in format of formatter

currDateTime = formatter.parseDateTime(currTime); //Converted to DateTime in UTC
