converting Date: header field to local timezone in pager?

[David Roche]

I've searched all over the docs, and can't figure out how to get the pager to
display all Date: header fields in time converted to the local timezone.  Is
this possible?

In other words, some mails from the UK dispay dates like this:
    Date: Wed, 17 May 2000 11:09:03 +0100
While mails from the US West Coast (my local timezone) display like this:
    Date: Wed, 17 May 2000 07:51:46 -0700 (PDT)

When displaying these two mails, I'd like to see:
    Date: Wed, 17 May 2000 03:09:03
    Date: Wed, 17 May 2000 07:51:46

Or, better yet:
    Date: Wed, 17 May 2000 03:09:03 (11:09:03 +0100)
    Date: Wed, 17 May 2000 07:51:46 (07:51:46 -0700 (PDT))

How can I accomplish this?

Thanks,
David Roche
