I use this to monitor the last modified tiddler (system & non-system) or last "cached" action in a state tiddler of the wiki which is usually the $:/HistoryList or $:/state/tab/sidebar-- it's the closest I have gotten to a wiki file save date/time without having to go beyond a simple list widget:
<$list filter="[all[tiddlers]!sort[modified]limit[1]]"> <$view field="title"/> - <$view field="modified" format="date" template="DD mmm YYYY 0hh:0mm"/><br/> </$list> -- You received this message because you are subscribed to the Google Groups "TiddlyWiki" group.
