I am using the method below but there is an hour difference in the converted timestamp
public static String getServerFormattedDate(String dateStr) {
Timestamp ts = new Timestamp(Long.valueOf(dateStr)); // input date in
// Timestamp
// format
SimpleDateFormat dateFormat = new SimpleDateFormat(
"yyyy-MM-dd HH:mm:ss");
Calendar cal = Calendar.getInstance();
cal.setTime(ts);
cal.add(Calendar.HOUR, +7); // Time different between UTC and PDT is +7
// hours
String convertedCal = dateFormat.format(cal.getTime()); // This String
// is converted
// datetime
/* Now convert String formatted DateTime to Timestamp */
return convertedCal;
}
Don't do timezone math on the timestamp yourself. Instead, keep it in UTC and set the timezone on the DateFormat
. For example:
SimpleDateFormat dateFormat = new SimpleDateFormat(
"yyyy-MM-dd HH:mm:ss");
dateFormat.setTimeZone(TimeZone.getTimeZone("PDT"));
Date date = new Date(Long.valueOf(dateStr));
String convertedCal = dateFormat.format(date);
By default SimpleDateFormat
uses timezone settings appropriate for the current default locale and that can explain the 1 hour difference you're seeing.
