With the circular graphic of relative amounts, the times are all the same at 33 minutes.

This seems to be a node related issue. Try switching to a different node in settings ;)

In the tab for curation rewards, the times are calculated from when the post was made to the current time (up to 6 days).

I need to make a few changes, because the nodes don't return the votes weight as it was before (I need to recalculate it first to get the correct amount of unclaimed rshares).

Many things on my list...
