I have been working with TAL, TALES, and METAL over the last few days - and I thought I was kind of "getting it." However, I've hit a small snag. Is there a way via TAL to get to many of the Zope methods I use all the time in DTML? like ZopeTime() or bobobase_modification_time?
This is one of the areas of TALES that is still developing. Right now, Python TALES expressions have the same collection of builtin functions available to them as Python-based Scripts, which is to say most of the functions that you access from DTML as attributes of "_". This needs a lot of documenting. The names you are accustomed to using in DTML can be roughly divided into three groups: 1. Namespace attributes, such as _.int, which are usable directly in ZPT. 2. DTML Tag variables, such as sequence-item. These don't exist in ZPT. 3. Object attributes/methods. Most of these, such as bobobase_modification_time, are specific to the object on which you invoke them. You'll get a different modification time for 'here', 'template', and 'root' (assuming that 'here' isn't the root). A few, such as ZopeTime, are generic functions.

Use "python:DateTime()" for this.
Congrats to the ZPT team for this breakthrough techology!
Thank you! Cheers, Evan @ digicool
