I really like the Trac project management software. Recently I have been using it very much and customizing it to fit my needs at work. In regards with the notification system, I found that the default format was not acceptable and a custom one was desired. I added the following code to the file "/usr/lib/python2.4/site-packages/trac/ticket/templates/ticket_notify_email.txt" to have a nice date in the template:

{% python

    from genshi.builder import tag
    from trac.util.datefmt import format_datetime
    import time

    def custom_time(value):
        return format_datetime(t=value, format='%H:%M:%S', tzinfo=PST)

%}

${custom_time(ticket.time)}

My entire file looks like the following:

{% python

    from genshi.builder import tag
    from trac.util.datefmt import format_datetime
    import time

    def custom_time(value):
	return format_datetime(t=value, format='%Y-%m-%d %H:%M:%S', tzinfo=PST)

%}
{% choose ticket.new %}\
{%   when True %}\
On ${custom_time(ticket.time)} PST, a ticket with the summary of '$ticket.summary' was created by '$ticket.reporter' and assigned to $ticket.owner .
{%   end %}\
{%   otherwise %}\
{%     if changes_body %}\
${_('Changes (by %(author)s):', author=change.author)}

$changes_body
{%     end %}\
{%     if changes_descr %}\
{%       if not changes_body and not change.comment and change.author %}\
${_('Description changed by %(author)s:', author=change.author)}
{%       end %}\
$changes_descr
--
{%     end %}\
{%     if change.comment %}\

${changes_body and _('Comment:') or _('Comment (by %(author)s):', author=change.author)}

$change.comment
{%     end %}\
{%   end %}\
{% end %}\

--
${_('Ticket URL: <%(link)s>', link=ticket.link)}
$project.name <${project.url or abs_href()}>
$project.descr
