[imp] UT date headers not displaying properly

[Jaap Winius]

Hi all,

Recently I noticed that IMP4 (v4.1.5) has a problem interpreting a  
certain date header format:

    Date: Tue, 23 Oct 2007 07:15:07 UT

In this case, IMP4 will display "Unknown Date" for such messages when listing
the contents of a folder. However, when the message itself is opened,  
the date displays properly (same as above). IMP3 does not have this  
problem, nor does
Alpine when viewing the same messages on the same system.

Is this a known bug?

Cheers,

Jaap
