[jbpm-issues] [JBoss JIRA] Commented: (JBPM-1446) display non GMT+0 time zones

[Alejandro Guizar (JIRA)]

    [ https://jira.jboss.org/jira/browse/JBPM-1446?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12424127#action_12424127 ] 

Alejandro Guizar commented on JBPM-1446:
----------------------------------------

Quoting the Oracle page:

"Timezone can be set per web-app in adf-faces-config.xml configuration file. If timeZone is not set on the converter, then timezone will be defaulted to the value set in adf-faces-config.xml configuration file. If it is not set in the configuration file, then it will be defaulted to GMT."

The client time zone is not mentioned anywhere. In turn, the IBM page does not mention what the time zone defaults to. Since it reads "the <hx:convertDateTime> tag extends the <f:convertDateTime> tag" I assume it simply defaults to GMT just like the standard faces tag.

In both cases, the locale attribute specifies the "locale whose predefined styles for dates and times are used during formatting or parsing". If not specified, FacesContext.getViewRoot().getLocale() is used instead. No relation between the locale and the time zone is ever established.

As for Seam, the documentation (as well as the code, which I understand now) reads:

"There is also a session-scoped instance of  java.util.Timezone, named org.jboss.seam.international.timezone, and a Seam component for changing the timezone named  org.jboss.seam.international.timezoneSelector. By default, the timezone is the default timezone of the server. Seam provides the <s:convertDateTime> tag which always performs conversions in the Seam timezone."

(from http://docs.jboss.com/seam/2.0.2.SP1/reference/en-US/html/i18n.html#d0e9255)

In sum it seems the best default you can get is the server time zone. You can provide a way to set a default time zone per web app in a configuration file. You can associate the time zone to the session and allow the client to change it at a single point. But there is no hope of getting your hands on the client time zone.
