To begin with, Date of pipermail was not RFC2822 form. 
However, Date of pipermail is correctly reflected in the field 'Date'.

Then, let's examine the time stamp of pipermail file next. 
For instance, please confirm the following file and confirm the date
by 'ls -alF'. 

    /pipermail/kca/2002-September/000192.html
    /pipermail/kca/2002-July/000052.html
    /pipermail/kca/2002-August/000103.html
    /pipermail/kca/2003-March/000353.html
    /pipermail/kca/2003-January/000331.html

It might be not corresponding to Date of the content of the time stamp 
and the file. 

The date sorting is a function to sort the time order of the stamp. 
There are two kinds of methods of solving this problem. 

One is a method of changing the time stamp of the file according 
to information on Date of contents of the file. 

Another one is a method of using the field sorting UTC function. 
Do you know the method of setting the field sorting UTC function?
