For all the date, it seems to remove one day. When I click on 8 nov, it displays 11/08/2011. But then it stores Nov 7, 2011 in my Date field in my manag

Answer 1

try adding this to your web.xml

<context-param>
    <param-name>javax.faces.DATETIMECONVERTER_DEFAULT_TIMEZONE_IS_SYSTEM_TIMEZONE</param-name>
    <param-value>true</param-value>
</context-param>

Answer 2

Maybe it is because you didn't insert the hours. For example in this case

<p:calendar id="dateFromCalendar"
    value="#{platform.frameBean.dateFrom}" showOn="button"
    pattern="dd-MM-yyyy" timeZone="Europe/Warsaw">
</p:calendar>

the hour will come as 00:00 of the actual day. And because the timezone (-02:00), the hour will appear as 22:00 of the day before the actual day. The correct thing to do is

<p:calendar id="dateFromCalendar"
    value="#{platform.frameBean.dateFrom}" showOn="button"
    pattern="dd-MM-yyyy HH:mm" timeZone="Europe/Warsaw">
</p:calendar>

The hour will appear, so the timezone will make the correct calculations

Answer 3

I have just added the following parameter in web.xml and the issue is fixed. I didn't include any command like -Duser.timezone=UTC while starting the server, still its fixed the issue.

javax.faces.DATETIMECONVERTER_DEFAULT_TIMEZONE_IS_SYSTEM_TIMEZONE true

Answer 4

In your calendar component, add a converter and indicate your timezone e.g

<p:calendar id="date">
  <f:convertDateTime timeZone="Asia/Singapore"></f:convertDateTime>
</p:calendar

Answer 5

If you are using primefaces 5, in your scheduler :

<p:schedule ...ignoreTimezone="false" />

Answer 6

Adding the argument -Duser.timezone=UTC to the startup parameters fixed problem for me.

To summarize: p:schedule work only well when following parameters are sets:

-Duser.timezone=UTC

<context-param>
    <param-name>javax.faces.DATETIMECONVERTER_DEFAULT_TIMEZONE_IS_SYSTEM_TIMEZONE</param-name>
    <param-value>true</param-value>
</context-param>
