Hi Piyush!
You can use expressions in Timer Intermediate Catching Event. For example, if your previous task sets myvariable to "PT5M", this timer event will wait for 5 minutes:
<code>
<intermediateCatchEvent id="timer">
<timerEventDefinition>
<timeDuration>${myvariable}</timeDuration>
</timerEventDefinition>
</intermediateCatchEvent>
</code>

What is wrong with the process definition given below

<process id="Timer1" name="Timer1" isExecutable="true">
    <startEvent id="startevent1" name="Start"></startEvent>
    <endEvent id="endevent1" name="End"></endEvent>
    <scriptTask id="scripttask1" name="Script Task" scriptFormat="javascript" activiti:autoStoreVariables="false">
      <script>java.lang.System.out.println("Testing");</script>
    </scriptTask>
    <sequenceFlow id="flow1003" sourceRef="scripttask1" targetRef="endevent1"></sequenceFlow>
    <intermediateCatchEvent id="timerintermediatecatchevent1" name="TimerCatchEvent">
      <timerEventDefinition>
        <timeDuration>PT100S</timeDuration>
      </timerEventDefinition>
    </intermediateCatchEvent>
    <sequenceFlow id="flow1004" sourceRef="startevent1" targetRef="timerintermediatecatchevent1"></sequenceFlow>
    <sequenceFlow id="flow1005" sourceRef="timerintermediatecatchevent1" targetRef="scripttask1"></sequenceFlow>
</process>

It does not wait and Script Task gets Executed Immediately.
