If you open a published event and make changes, then click Publish, it acts like it is updating the event and goes back to the events list where the time of the attempted update is shown as the "last modified" date. But when you open the item, the changes were not saved. Tried this several time not believing what I was seeing.
Got it to work by opening the item, unpublishing it, making the changes, then publishing. Ugh.
