I'm sorry, i should have been more thorough when reporting the bug.
You're right about the timestamp, they are stored correctly.
But it seems, that when you reopen the tournament director the next day, reopen the stored TD file and skip forward to the next round, the timestamp is somehow reset to the previous day. This messes up the ranking the way i described.
I'll add en exported TD file, so you can check it yourself. Compare the history log with the final ranking.

Pieter
