f:converterDateTime doesn't convert properly

[Susumu Majima]

I use JBOSS/Seam that includes Myface1.1.1.

When I try to show time it isn't shown properly.

the code snipped is below

<h:outputText value ="#{schedule0.sch_start">
   <f:convertDateTime pattern "HH:mm"/>
</h:outputText>

If actual data is 9:00 then shown date is 0:00.

I'm in Japan so the shown time is GMT time?

Is there any good way to  correct this problem or work around?
