Java - SimpleDateFormat wrong format

Question

In my Postgresql database, I have a timestamp without time zone with this value : "2012-06-15 17:49:46.423" (default datatype used by Hibernate).

If I format with SimpleDateFormat and this pattern "EEEE dd MMMM yyyy", SimpleDateFormat#format returns "jeudi 14 juin 2012".

Why the result is not "vendredi 15 juin 2012" ?

French to English translation for non-french spoken :

"jeudi 14 juin 2012"    => "Thursday 14th of June 2012"
"vendredi 15 juin 2012" => "Friday 15th of June 2012"

Hibernate 3.6.8.Final
JSF 2.0
JBoss 5.1.0.GA
Java 6

Thanks.

Timezone of the machine that is producing this result?

GMT +1 (JBoss side) , GMT +0200 (Postgresql)

Also "jeudi" is "Thursday", not "Tuesday."

It's showing you just one day ahead of what you expect. Reason might be server time which is on another time zone I guess. Anyways the below code is working fine:

SimpleDateFormat sdf = new SimpleDateFormat("EEEE dd MMMM yyyy", Locale.FRENCH);
System.out.println(sdf.format(new Date()));

After searching, it turns out that I had two main options. Either I set the time zone through Hibernate or JSF.

Option 1 : Hibernate
I could change access type to Property. So in the setter, I would adjust the timestamp value to the right time zone. Another solution would be to create a custom Hibernate User Type.

Full details with code here : Mapping Dates and Time Zones with Hibernate, Part 2: Few Solutions

Option 2 : JSF
Last option, I either create a custom converter in JSF or more simply, I use the timeZone attribute of f:convertDateTime.

This how I did it :

<h:outputText value="#{row.date}">
    <f:convertDateTime pattern="EEEE dd MMMM yyyy" locale="fr_FR" type="date" timeZone="Europe/Paris" />
</h:outputText>

All my dates are correct now !

SimpleDateFormat simpleDateFormat = new SimpleDateFormat("dd MMMM yyyy zzzz G", Locale.FRENCH);

try this

also printing out a date will automatically print formatted date text in machine time zone.
