I was going through the flagged posts review page in the 10k moderation tools and it is there that I happened to stumble upon what could possibly be a bug. I was amazed to see that the time which was displayed for the
joined field was actually lesser than the time which was displayed for by the
answered field. How is this possible? How can a user answer to any question even before joining Stack Overflow? Is it some sort of bug or what, because I don't think this is a valid scenario. Please have a look at the snapshot below to understand what exactly I meant.
How is this possible?
