How is LastBuildDate triggered

Hi,

I´m wondering, how is the LastBuildDate triggered at feed, when the show module is enabled? It seems that the LastBuildDate at the feed is generated at every feed when a podcast is published at one show. Should this be the common trigger?

I´ve opened a bug tracker ticket as it seems to be one or a not yet implemented feature: https://github.com/podlove/podlove-publisher/issues/1106
