The $action-setfield widget can update more than one field when pressed.
Thus, for your edit-text and button combination, you could write:
\define setrev() <$action-setfield $tiddler=<<currentTiddler>>
rev={{$:/temp/revinput}} revdate=<<now "YYYY0MM0DD0hh:0mm:0ss">> />
<$edit-text tiddler="$:/temp/revinput" tag="input" default="" />
<$button actions=<<setrev>>> set revision </$button>
Note: use the actions=... button parameter to invoke the action-setfield
widget. This allows the value of revdate to be calculated each time the
button is pressed.
