Gnucash's SQL backend stores dates in UTC and converts  them to local time for the UI.
When you enter a date in the Price editor (which can take only dates), it's set to midnight (00:00)
of that day.  Finance::Quote provides its own timestamps which include the time. It appears that
you local timezone is UTC +2 given that the date you entered is recorded as 2 hours before 
midnight. You're probably getting quotes from European or American markets, neither of 
which are (yet) open at a time that would record UTC dates the day before. If you test with
Asian markets quotes (Hong Kong, Tokyo, Shanghai, etc.) between midnight and 0200 your
time you may see the same effect.
