DateTime in Plone 3

Back in the days of Plone 2.x, page templates used to be able to just access Zope's DateTime module like this:

<b tal:content="DateTime()" />

This would give you the current date and time.

In Plone 3.x, this ability disappeared. Now, I'm confident that people wiser than I made this decision, but sometimes I want it back. Imagine my delight when, whilst perusing Plone's advanced search form, I found this little beauty:

<form tal:define="DateTime python:modules['DateTime'].DateTime">
...
</form>

Ker-ching.
