I found the following in the CSS3 spec for generated content in paged media (http://www.w3.org/TR/css3-gcpm/):

‘env()’
This function returns data from the local environment of the user at the time of formatting. The function accepts one of these keywords:

* env(url): returns the URL of the document
* env(date): returns the date on the user's system at the time of formatting
* env(time): returns the time on the user's system at the time of formatting
* env(date-time): returns the date and time on the user's system at the time of formatting

This would be very helpful for generating slug lines similar to those used in Quark/InDesign. We already do simple slug lines using a large negative margin on @bottom-right to keep it outside the trim (we are using crop/cross marks and bleed):

@bottom-right {
vertical-align: bottom;
margin-bottom: -40pt;
content: 'Book Title, page ' counter(page);
}

But we'd love to have a date and time stamp included in the slug as well.

Thanks,

In Prince 8.0, dates can be manipulated using JavaScript and included in CSS generated content using the prince-script() value:

<style>
span.date { content: prince-script(getDate) }
</style>
<script>
function getDate()
{
    return (new Date()).toString();
}
</script>
