Caching and Customfield PHP update problem

Hello!

I have an event calendar and a view that displays upcoming events above blog posts. These upcoming events display "Tomorrow", "Day after tomorrow", "Friday" and so on. I achieved this by having a Customfield with PHP code which works okay.

The problem is that it does not always update and an event reminder might be "tomorrow" even it's today.

- If I log in it displays correctly.
- The problem is solved temporarily when I click Empty Views Cache on views settings.
- I have set the Cache: none for this view - doesn't seem to make a difference
