# Optional settings ### Referencing Historic Events The event for which the speaker/lecture/... data is displayed is determined by its organization ID, which you set in the Wordpress admin interface. However, you can override this setting in a shortcode in order to display last year's speakers, for example. All shortcodes accept an optional `org-id="..."`argument, so for example ``` [talque-speaker-grid org-id="xyz123"] ``` will display the speakers from the event whose id is `xyz123`. ### Timezone override The timezone of your event is set in the talque admin interface. By default, this timezone settings is used to display all dates and times in the javascript plugin. However, you can override the timezone with the optional shortcode attribute `timezone="..."` argument, for example * `timezone="Europe/Berlin"` for central europe * `timezone="America/New_York"` for US east coast and so on. The appropriate daylight savings time adjustment is automatically applied according to the date, you do not have to do anything special. The name of the timezone is the usual timezone database name, sometimes also called Olsen name.
