I am using Magento Enterprise 1.10.1.1 and need to get some dynamic
content on our product pages. I am inserting the current time in a block to quickly see if it is working, but can't seem to get through full page cache.
I have tried a variety of implementations found here:

Any solutions, thoughts, comments, advice is welcome.
