Converting Time to Multiple Timezones

Date startTime = new Date(); // current date time

TimeZone pstTimeZone = TimeZone.getTimeZone("America/Los_Angeles");

DateFormat formatter = DateFormat.getDateInstance(); // just date, you might want something else

formatter.setTimeZone(pstTimeZone);

String formattedDate = formatter.format(startTime);

OR 

TimeZone pacificTimeZone = TimeZone.getTimeZone("America/Los_Angeles");

long currentTime = new Date().getTime();

long convertedTime = currentTime +

pacificTimeZone.getOffset(currentTime);
