java - SimpleDateFormat parse loses timezone -


code:

 simpledateformat sdf = new simpledateformat("yyyy.mm.dd hh:mm:ss z");     sdf.settimezone(timezone.gettimezone("gmt"));     system.out.println(new date());     try {         string d = sdf.format(new date());         system.out.println(d);         system.out.println(sdf.parse(d));     } catch (exception e) {         e.printstacktrace();  //to change body of catch statement use file | settings | file templates.     }

output: 

thu aug 08 17:26:32 gmt+08:00 2013 2013.08.08 09:26:32 gmt thu aug 08 17:26:32 gmt+08:00 2013

note format() formats date correctly gmt, parse() lost gmt details. know can use substring() , work around this, reason underlying phenomenon?

here duplicate question doesn't have answers.

edit: let me put question in way, way retrieve date object in gmt?

all needed : 

simpledateformat sdf = new simpledateformat("yyyy.mm.dd hh:mm:ss"); sdf.settimezone(timezone.gettimezone("gmt"));  simpledateformat sdflocal = new simpledateformat("yyyy.mm.dd hh:mm:ss");  try {     string d = sdf.format(new date());     system.out.println(d);     system.out.println(sdflocal.parse(d)); } catch (exception e) {     e.printstacktrace();  //to change body of catch statement use file | settings | file templates. }

output : dubious, want date consistent

Java, Hibernate, MySQL - store UTC date-time -

i saw here on few related questions (like this one , of course, this one )... essentially, want store date-time utc, , let application user choose time zone wants display date-time in. since seems date-time fields affected underlying jdbc driver, wonder if acceptable way go storing utc date-time: set both mysql , application server machine utc time zone (no need separate) both mysql , jvm should pick underlying system time settings (if not instructed otherwise) use datetime table columns on mysql side use java.util.date corresponding mapping on hibernate side (i guess java.sql.timestamp used too) let application worry interpreting date-time fields - i.e. let user choose preferred time zone is ok? edit clarify - here meant refer timestamps created strictly on server (e.g.date-time of record creation). application server instantiates date objects (new date() equals current date-time on server, , time zone agnostic). if client user wants supply date searching/filte...
