My TiddlyTools Timer functions can do this. 1) Copy the $action-timeout widget from http://tiddlytools.com/timer.html#TiddlyTools%2FTime%2Faction-timeout.js <http://tiddlytools.com/timer.html#TiddlyTools%2FTime%2Faction-timeout.js> 2) Create a "MinuteTickerStartup" tiddler, tagged with *$:/tags/StartupAction*, containing: \define minute_ticker() <$action-setfield $tiddler="$:/temp/time/minuteticker" text=<<now [UTC]0hh0mm0ss>> /> <$action-timeout interval=60000 actions=<<minute_ticker>> /> 3) In a tiddler tagged with *$:/tags/PageTemplate*, put the content you want to automatically re-render each minute, like this: <$vars ticker={{$:/temp/time/minuteticker}}> *** content you want to re-render *** </$vars> Notes: 1) MinuteTickerStartup is invoked *once* when you load your TiddlyWiki and sets up an javascript "interval" timer that is triggered every minute (60000 milliseconds) 2) The ticker action updates the contents of *$:/temp/time/minuteticker* to contain the current time (0hh0mm0ss) 3) The $vars "wrapper" in the page template tiddler creates a refresh dependency associated with the current value in *$:/temp/time/minuteticker* The result is that whatever content is in your page template will be re-rendered once per minute.
