Custom date formats no longer available

I've created a few posts about this some time back and I believe it's more of a Token issue than an issue with Custom Formatters. But I'm hoping you might be able to provide some guidance, not just to me, but to others who are having the same problem.

After performing site upgrades, tokens for custom display of CCK dates are no longer available. In my case, I have a "published date" displayed in a mini-calendar format, using the HTML below:

<div class="calendar-icon"><div class="month">[node:field-published-date:custom:M]</div>
<div class="day">[node:field-published-date:custom:j]</div>
<div class="year">[node:field-published-date:custom:Y]</div></div>

This no longer works.

I've tried installing http://drupal.org/project/token_formatters but it doesn't seem to do anything - in any event, I'm wondering if you might be able to provide some guidance as to how the same thing might be accomplished using PHP (if possible) and/or if I should create another issue in the Tokens issue queue. And if I create an issue over there, perhaps you could give me some guidance as to best describe what's happening - or not happening, as the case may be.

Thank you for the module and for your assistance - Happy Merry!
