I had a bounty on Asymmetric Hessian matrix, started "jun 17 at 9:27", as can be seen for instance from the last modified date on the asker's page. It is now approximately 18:10 on June 23, and the bounty seems to have already expired. Shouldn't it go until around 9:27 on June 24?
This is a very minor concern, but
I'm wondering if this is working how it is supposed to it seems to be a bug.
Added: I had briefly searched before asking, but apparently not very well. Since posting I found a very similar bug report on meta.stackoverflow.com: Bounty expired before the expiry time?
I also discovered that the bounty start and end shows up in the revision history, so I can confirm that it ended about a day early, at 9:28:36 on June 23.
