Converting date from UTC to EST in Java?

Question

I'm trying to convert a long timestamp that is UTC to Eastern Standard Time and am totally lost. Any hints would be great! Time format should be : 11/4/03 8:14 PM Thanks in advance! TimeZone utcTZ= TimeZone.getTimeZone("UTC"); Calendar utcCal= Calendar.getInstance(utcTZ); utcCal.setTimeInMillis(utcAsLongValue); import java.text.SimpleDateFormat; import java.util.Date; SimpleDateFormat sdf= new SimpleDateFormat("yyyy-MM-dd HH:mm:ss zzz"); sdf.setTimeZone(utcTZ); Date utcDate= utcCal.getTime(); sdf.formatDate(utcDate); JavaScript questions and answers, JavaScript questions pdf, JavaScript question bank, JavaScript questions and answers pdf, mcq on JavaScript pdf, JavaScript questions and solutions, JavaScript mcq Test , Interview JavaScript questions, JavaScript Questions for Interview, JavaScript MCQ (Multiple Choice Questions)

Answer 1

Yesterday occasionally I wrote the following method that can help you: private Date shiftTimeZone(Date date, TimeZone sourceTimeZone, TimeZone targetTimeZone) { Calendar sourceCalendar = Calendar.getInstance(); sourceCalendar.setTime(date); sourceCalendar.setTimeZone(sourceTimeZone); Calendar targetCalendar = Calendar.getInstance(); for (int field : new int[] {Calendar.YEAR, Calendar.MONTH, Calendar.DAY_OF_MONTH, Calendar.HOUR, Calendar.MINUTE, Calendar.SECOND, Calendar.MILLISECOND}) { targetCalendar.set(field, sourceCalendar.get(field)); } targetCalendar.setTimeZone(targetTimeZone); return targetCalendar.getTime(); } Now you just have to format the date. Use SimpleDateFormat for this. Here is the example: DateFormat format = new SimpleDateFormat("dd/MM/yy hh:mm a"); format.format(date);
