Thanks, we will check it

after refresh the page, does it be correct?

@UserSupport No. Negative values remain negative after page refresh. Passage of ~20000 seconds raises the value above zero.  It appears to be a timezone issue. It appears to be not entirely harmless to have future dated events, but I didn't capture any specific symptoms. For a weak example, note that one of the projects is called "mysteriously renamed" because I don't recall what the original name was. It is an older project that got renamed somehow in the course of some process of naming a new project that I don't recall in detail. There were other anomalies with project creation, naming & access around the same time.
