Set TransactTime property value to the current EST Timestamp. Then calculate ExpireTime = TransactTime + 5 hours.
<java classname="Timestamp" outputproperty="TransactTime" fork="false" />
<math result="ExpireTime" operation="+" operand1="${TransactTime}" operand2="18000000" datatype="long"/>
Set TransactTime property value to the current GMT Time plus 5 hours..
<tstamp>
<format property="TransactTime" pattern="yyyyMMdd-HH:mm:ss.SSS" timezone="GMT" unit="hour" offset="5"/>
</tstamp>
