How to append the timestamp in log4j.xml

Question

Hi,
Has anybody know how to configure the timestamp in log4j.xml??
It would be great, if you could update the right parameter name in my log4.xml which appears below to display timestamp in my log file Master.log!
<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE log4j:configuration SYSTEM "log4j.dtd">
<log4j:configuration
  xmlns:log4j="http://jakarta.apache.org/log4j/">
  <!-- Order of child elements is appender*, logger*, root?. -->
  <!-- Appenders control how logging is output. -->
  <appender name="CM" class="org.apache.log4j.FileAppender">
     <param name="File" value="Master.log"/>
     <param name="Threshold" value="DEBUG"/>
     <param name="Append" value="true"/>
     <param name="MaxFileSize" value="1MB"/>
     <param name="MaxBackupIndex" value="1"/>
    <layout class="org.apache.log4j.PatternLayout">
      <!-- {fully-qualified-class-name}:{method-name}:{line-number}
            - {message}{newline} -->
      <param name="ConversionPattern" value="%C:%M:%L - %m%n"/>
    </layout>     
  </appender>
  <appender name="stdout" class="org.apache.log4j.ConsoleAppender">
    <param name="Threshold" value="INFO"/>
    <layout class="org.apache.log4j.PatternLayout">
      <param name="ConversionPattern" value="%C:%M:%L - %m%n"/>
    </layout>
  </appender>
  <!-- Logger hierarchy example:
       root - com - com.ociweb - com.ociweb.demo - com.ociweb.demo.LogJDemo
  -->
  <!-- Setting additivity to false prevents ancestor categories
       for being used in addition to this one. -->
  <logger name="com.tf" additivity="true">
    <priority value="DEBUG"/>
    <appender-ref ref="CM"/>
  </logger>
  <!-- Levels from lowest to highest are
       trace, debug, info, warn, error, fatal & off. -->
  <!-- The root category is used for all loggers
       unless a more specific logger matches. -->
  <root>
    <appender-ref ref="stdout"/>
  </root>
</log4j:configuration>

Hello Sir,
I have configured Log4j.xml for my project and it is able to generate the log file properly with the timestamp,but it is showing the the following error messaged at weblogic console!
log4j:ERROR Parsing error on line 3 and column 8
log4j:ERROR Element type "log4j" must be declared.
log4j:ERROR Parsing error on line 15 and column 13
log4j:ERROR The content of element type "appender" must match "(errorHandler?,param*,layout?,filter*,appender-ref*)".
log4j:ERROR Parsing error on line 16 and column 57
log4j:ERROR Attribute "priority" must be declared for element type "category".
log4j:ERROR Parsing error on line 19 and column 25
log4j:ERROR Attribute "priority" must be declared for element type "root".log4j:ERROR Parsing error on line 39 and column 12
log4j:ERROR The content of element type "logger" must match "(level?,appender-ref*)".
log4j:WARN No such property [maxFileSize] in org.apache.log4j.DailyRollingFileAppender.
log4j:WARN No such property [maxBackupIndex] in org.apache.log4j.DailyRollingFileAppender.
Here is my Log4j.xml
<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE log4j:configuration SYSTEM "log4j.dtd">
<log4j:configuration
xmlns:log4j="http://jakarta.apache.org/log4j/">
<!-- Order of child elements is appender*, logger*, root?. -->
<!-- Appenders control how logging is output. -->
<appender name="CM" class="org.apache.log4j.DailyRollingFileAppender">
     <param name="File" value="Customer_Master.log"/>
     <param name="Threshold" value="DEBUG"/>
     <param name="Append" value="false"/>
     <param name="DatePattern" value="'.'yyyy-MM-dd"/>
     <param name="MaxFileSize" value="1MB"/>
     <param name="MaxBackupIndex" value="1"/>
<layout class="org.apache.log4j.PatternLayout">
<!-- {fully-qualified-class-name}:{method-name}:{line-number}
- {message}{newline} -->
<param name="ConversionPattern" value="%d %-5p [%c] %m%n"/>
</layout>
</appender>
<appender name="stdout" class="org.apache.log4j.ConsoleAppender">
<param name="Threshold" value="INFO"/>
<layout class="org.apache.log4j.PatternLayout">
<param name="ConversionPattern" value="%C:%M:%L - %m%n"/>
</layout>
</appender>
<!-- Logger hierarchy example:
root - com - com.ociweb - com.ociweb.demo - com.ociweb.demo.LogJDemo
-->
<!-- Setting additivity to false prevents ancestor categories
for being used in addition to this one. -->
<logger name="com.tf" additivity="true">
<priority value="DEBUG"/>
<appender-ref ref="CM"/>
</logger>
<!-- Levels from lowest to highest are
trace, debug, info, warn, error, fatal & off. -->
<!-- The root category is used for all loggers

<root>
<appender-ref ref="stdout"/>
</root>
</log4j:configuration>
It would be great,if you could correct the above xml file and avoid getting the error message from Weblogic console.
Thanks in advance,
