datepicker - The day name showing incorrect value, next day or previous day in Android - 


public class main extends activity {         protected static final int dialog = 0;     private int day;     private int month;     private int year;     button mbt;      @override     protected void oncreate(bundle savedinstancestate) {         super.oncreate(savedinstancestate);         setcontentview(r.layout.main);         mbt = (button) findviewbyid(r.id.button1);         mbt.setonclicklistener(new onclicklistener() {         public void onclick(view arg0) {             showdialog(dialog);         }         });     }      private void  updatedisplay() {         string day = (dateformat.format("eeeeee", new date(year, month, day))).tostring();         toast.maketext(main.this, day, toast.length_long).show();     }      private datepickerdialog.ondatesetlistener      mdatesetlistener = new datepickerdialog.ondatesetlistener() {         @override         public void ondateset(datepicker arg0, int year, int monthofyear, int dayofmonth) {             year = year;             month = monthofyear;             day = dayofmonth;             updatedisplay();         }     };      protected dialog oncreatedialog(int id){         switch(id) {             case dialog:                 return new datepickerdialog(this ,mdatesetlistener ,year , month , day);         }         return null;     } }

when select date, android modifies date own timezone, should create calendar type variable using, calendar.getinstance(timezone.getdefault()) , issue calendar.set(int year, int month, int day). http://developer.android.com/reference/java/util/calendar.html if unsure something! :)

correct code be:

public class main extends activity {     protected static final int dialog = 0; private int day; private calendar c; private int month; private int year;      button mbt;      @override     protected void oncreate(bundle savedinstancestate) {         super.oncreate(savedinstancestate);         setcontentview(r.layout.main);         c = new calendar(timezone.getdefault());         mbt = (button) findviewbyid(r.id.button1);         mbt.setonclicklistener(new onclicklistener() {         public void onclick(view arg0) {             showdialog(dialog);         }         });     }      private void  updatedisplay() {         string day = c.getdisplayname(calendar.day_of_week, calendar.long, locale.getdefault());         toast.maketext(main.this, day, toast.length_long).show();     }      private datepickerdialog.ondatesetlistener      mdatesetlistener = new datepickerdialog.ondatesetlistener() {         @override         public void ondateset(datepicker arg0, int year, int monthofyear, int dayofmonth) {             year = year;             month = monthofyear;             day = dayofmonth;             c.set(year, month, day);             updatedisplay();         }     };      protected dialog oncreatedialog(int id){         switch(id) {             case dialog:                 return new datepickerdialog(this ,mdatesetlistener ,year , month , day);         }         return null;     } }

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...
