[Zope] mailhost localzone error

[AM]

When I try to use the following:

<dtml-sendmail mailhost="mail_host">
To: list_subscriber@neurobs.com
From: list_subscriber@neurobs.com
Subject: test

Dear test,

You order number dadada is ready.
Please pick it up at your soonest convenience.
</dtml-sendmail>


for my MailHost object mail_host I get the following:

Traceback (innermost last):

    * Module ZPublisher.Publish, line 98, in publish
    * Module ZPublisher.mapply, line 88, in mapply
    * Module ZPublisher.Publish, line 39, in call_object

    * Module Products.MailHost.MailHost, line 208, in _mungeHeaders
    * Module DateTime.DateTime, line 1441, in rfc822

NameError: global name 'localzone' is not defined

Any ideas as what has gone wrong with my mailhost.

TIA
AM
