[Zope] Newbie question : ZopeTime & permissions

[Aaron Straup Cope]

Hi,

My name is Aaron.

I am trying to set up zope with (atleast) three roles : manager, admin,
user.

I'd like to give the last two the bare minimum Security permissions
possible and adding them as needed later on. 

My problem is that I can't seem to figure out, specifically, which
permissions to give a user that will allow them to read ZopeTime().

(see below)

For the admin user, I have set the Access content information and View *
options globally. I've tried guessing at some others, but there are alot
of possible combinations to try so I thought maybe I would just ask.

Related, is there a detailed description of the default Security
settings? I've checked the mailing lists and the Zope docs and if it's
there, I guess I missed it.

Thanks,

<dtml-call "REQUEST.set('ts', ZopeTime())">
<dtml-call "REQUEST.set('foo',_.str(_.int(ts)))">

<dtml-var foo>
