I looked into it and discovered that my default TimeZone is being set to: sun.util.calendar.ZoneInfo[id="GMT-08:00", offset=-28800000, dstSavings=0, useDaylight=false, transitions=0, lastRule=null] Rather than the Pacific time zone.

问题 Trying to output a list of items in a datatable, like this: <t:dataTable value="#{mybean.list}" var="item"> <h:column> <h:outputText value="#{item.time}"> <f:convertDateTime pattern="yyyy-MM-dd HH:mm:ssZ" timeZone="#{item.timeZone}" /> </h:outputText> </h:column> </t:dataTable> It always formats the time in GMT.

问题 Is there an exhaustive list of MySQL Time Zones?
