How to deal with visualization of java.util.Date with a custom timezone in JSF


How to deal with visualization of java.util.Date with a custom timezone in JSF

wish of those help Finally I found a different solution, based on the fact that it is not necessary to keep the original timezone the ticket was created for. I now simply use java.util.Date in the backing bean for the date picker component and convert it to an java.time.Instant as soon as I push it to the backend. For visualization purposes on the JSF frontend I just format the java.util.Date with a SimpleDateFormatter where I set the timezone to the one configured in the backend
code :
String timeZoneOffset = "GMT+0100";
TimeZone timeZone = TimeZone.getTimeZone(timeZoneOffset);
DateFormat dateTimeFormat = new SimpleDateFormat("yyyy-MM-dd'T'hh:mm:ss.SSSZ");
dateTimeFormat.setTimeZone(this.timeZone);
<p:outputLabel id="tripEndDate" value="#{registerBean.trip.tripEndDate}">
    <f:convertDateTime pattern="yyyy-MM-dd HH:mm Z" timeZone="#{registerBean.timeZone.getID()}" />
</p:outputLabel>

java.util.Date is timezone-independent. Says so right in the javadoc.

wish help you to fix your issue The date itself doesn't have any time zone. Its toString() method uses the current default time zone to return a String representing this date:
code :
Date date = new Date();

System.out.println(TimeZone.getDefault());
System.out.println(date);

TimeZone.setDefault(TimeZone.getTimeZone("UTC"));

System.out.println(TimeZone.getDefault());
System.out.println(date);
sun.util.calendar.ZoneInfo[id="Europe/Paris",offset=3600000,dstSavings=3600000,useDaylight=true,transitions=184,lastRule=java.util.SimpleTimeZone[id=Europe/Paris,offset=3600000,dstSavings=3600000,useDaylight=true,startYear=0,startMode=2,startMonth=2,startDay=-1,startDayOfWeek=1,startTime=3600000,startTimeMode=2,endMode=2,endMonth=9,endDay=-1,endDayOfWeek=1,endTime=3600000,endTimeMode=2]]

Apache CXF how to handle date conversion xsd:date to java.util.Date without timezone

Hope that helps Here is my problem with CXF. I have a SOAP1.2 service written in CXF. The service isn't complicated, it basically puts an XML int DB (Oracle 11.x). All the dates in WSDL are defined as xsd:date. , I've came up with this
code :
import java.util.Date;
import java.text.SimpleDateFormat;

import org.apache.cxf.xjc.runtime.DataTypeAdapter;

public class DateTypeAdapterWrapper {

    private static final String DATE_FORMAT = "yyyy-MM-dd";

    public static Date parseDate(String value) {
        return (DataTypeAdapter.parseDate(value));
    }

    public static String printDate(Date value) {
        String tmp = DataTypeAdapter.printDate(value);
        if(tmp == null) {
            return null;
        }
        SimpleDateFormat dateFormat = new SimpleDateFormat(DATE_FORMAT);
        return dateFormat.format(value);
    }
}

like below fixes the issue Interesting question.
When PostgreSQL's JDBC driver reads a column of type timestamp without time zone, it can usually read it to a java.sql.Timestamp or java.util.Date.

wish of those help java.util.Date does not store any time zone. It just stores the number of milliseconds since the 'epoch', which is 1 January 1970, 00:00:00 UTC.
Thus, all you have to do is to know the time zone of your server machine, find the period between this time zone and the time zone you want to convert it to and add or subtract the period.
code :
int clientGMT = 4; //GMT you want to convert to
int serverGMT = 2; //server's GMT
int delta = clientGMT - serverGMT; //delta between the dates

//assume this is the date in GMT + 2 received from the server
Date d1 = new SimpleDateFormat("dd.MM.yyyy hh:mm:ss").parse("12.03.2019 13:00:00");

//... and you want to convert it to GMT + 4 (client side's time zone)
Date resultDate = new Date(d1.getTime() + delta * 3600000);
