I have a field that is defined as TIMESTAMP WITH TIME ZONE.
The value to be saved starts off as: "09-23-2019 10:03:11 pm" in the zone of US/Hawaii.
This is what I am trying to save to the DB (all of the date information plus the Zone)
The database stores time information in UTC format.
As of now, the date is being stored in the DB so that it looks like this:
DAYS
---------------------------------------------------------------------------
23-SEP-19 10.03.11.000000 PM -05:00
23-SEP-19 10.03.11.000000 PM -05:00
During the processing, it runs through this code:
dateStr: the date (as seen above)
ZoneLoc: 'US/Hawaii'
public Calendar convDateStrWithZoneTOCalendar(String dateStr,
String ZoneLoc) throws Exception {
// convert the string sent in from user (which uses AM/PM) to one that uses military time (24HR)
// it
String formattedDate = null;
DateFormat readFormat = new SimpleDateFormat(this.getPattern());
DateFormat writeFormat = new SimpleDateFormat("MM-dd-yyyy'T'HH:mm:ss'Z'");
writeFormat.setTimeZone(TimeZone.getTimeZone(ZoneLoc));
Date date = null;
date = readFormat.parse(dateStr);
formattedDate = writeFormat.format(date);
// see if you can parse the date needed WITH the TimeZone
Date d;
SimpleDateFormat sdf = new SimpleDateFormat("MM-dd-yyyy'T'HH:mm:ss'Z'");
sdf.setTimeZone(TimeZone.getTimeZone(ZoneLoc));
d = sdf.parse(formattedDate);
Calendar cal = Calendar.getInstance();
cal.setTime(d);
system.out.println(" ZONELOC VALUE " + ZoneLoc);
system.out.println(" RETURNED VALUE " + cal );
return cal;
}
The calendar info that is returned is:
ZONELOC VALUE IS US/Hawaii
RETURNED VALUE IS java.util.GregorianCalendar[time=1577678591000,areFieldsSet=true,areAllFieldsSet=true,lenient=true,zone=sun.util.calendar.ZoneInfo[id="America/Chicago",offset=-21600000,dstSavings=3600000,useDaylight=true,transitions=235,lastRule=java.util.SimpleTimeZone[id=America/Chicago,offset=-21600000,dstSavings=3600000,useDaylight=true,startYear=0,startMode=3,startMonth=2,startDay=8,startDayOfWeek=1,startTime=7200000,startTimeMode=0,endMode=3,endMonth=10,endDay=1,endDayOfWeek=1,endTime=7200000,endTimeMode=0]],firstDayOfWeek=1,minimalDaysInFirstWeek=1,ERA=1,YEAR=2019,MONTH=11,WEEK_OF_YEAR=1,WEEK_OF_MONTH=5,DAY_OF_MONTH=29,DAY_OF_YEAR=363,DAY_OF_WEEK=1,DAY_OF_WEEK_IN_MONTH=5,AM_PM=1,HOUR=10,HOUR_OF_DAY=22,MINUTE=3,SECOND=11,MILLISECOND=0,ZONE_OFFSET=-21600000,DST_OFFSET=0]
It looks as though US/Hawaii is not being set in the RETURNED VALUE.
What can I do to be sure that this gets set?
After that, I can place it in the DB and see if the setting will "stick" and not revert back to America/Chicago
Update @Patrick H - thanks for the input. I made the change with the pattern you specified and was able to save the data. It now looks like this:
2017-08-02 13:38:49 TRACE o.h.type.descriptor.sql.BasicBinder - binding parameter [26] as [TIMESTAMP] - [java.util.GregorianCalendar[time=1569294191000,areFieldsSet=true,areAllFieldsSet=true,lenient=true,zone=sun.util.calendar.ZoneInfo[id="America/Chicago",offset=-21600000,dstSavings=3600000,useDaylight=true,transitions=235,lastRule=java.util.SimpleTimeZone[id=America/Chicago,offset=-21600000,dstSavings=3600000,useDaylight=true,startYear=0,startMode=3,startMonth=2,startDay=8,startDayOfWeek=1,startTime=7200000,startTimeMode=0,endMode=3,endMonth=10,endDay=1,endDayOfWeek=1,endTime=7200000,endTimeMode=0]],firstDayOfWeek=1,minimalDaysInFirstWeek=1,ERA=1,YEAR=2019,MONTH=8,WEEK_OF_YEAR=39,WEEK_OF_MONTH=4,DAY_OF_MONTH=23,DAY_OF_YEAR=266,DAY_OF_WEEK=2,DAY_OF_WEEK_IN_MONTH=4,AM_PM=1,HOUR=10,HOUR_OF_DAY=22,MINUTE=3,SECOND=11,MILLISECOND=0,ZONE_OFFSET=-21600000,DST_OFFSET=3600000]]
The data in the DB looks like this:
23-SEP-19 10.03.11.000000 PM -05:00
The Zone is still America/Chicago even through US/Hawaii was specified. How can one get US/Hawaii to stick and not revert back to America/Chicago?
