</h:outputText>
bean.setMyTimestamp(LocalDateTime.now());
Specifies what contents the string value will be formatted to include, or parsed expecting. Valid values are "date", "time", "both", "localDate", "localDateTime", "localTime", "offsetTime", "offsetDateTime", and "zonedDateTime". convertDateTime (JSF 2.3 View Declaration Language: Facelets Variant, generated with VDLDoc.)
Cela fonctionnera
<h:outputText value="#{bean.myTimestamp}" >
<f:convertDateTime pattern="yyyy/MM/dd HH:mm" timeZone="Japan" type="localDateTime" />
</h:outputText>
Je m'inquiète pour quelque chose ...
Je ne l'ai pas fait mais depuis un jour
