The <clock> element works like any other stimulus element (<text>, <picture>, <video>). Set it up and configure it according to your needs and have a <trial> display it.
<expt>
/ blocks = [1=a; 2=break; 3=b]
</expt>
<block a>
/ trials = [1-10=mytrial]
</block>
<block b>
/ trials = [1-10=mytrial]
</block>
<trial mytrial>
/ stimulusframes = [1=mytext]
/ validresponse = (57)
</trial>
<text mytext>
/ items = ("Press the spacebar as quickly as possible.")
</text>
<block break>
/ trials = [1=breaktrial]
</block>
<trial breaktrial>
/ stimulusframes = [1=breaktext, myclock]
/ validresponse = (0)
/ trialduration = 10000
</trial>
<text breaktext>
/ items = ("Take a break!")
/ position = (50%, 40%)
</text>
<clock myclock>
/ mode = timer
/ timeout = 10000
</clock>
