[Qt-interest] Strange problem storing and retrieving and comparing QTime/QDataTime

[Mihail Naydenov]

Thank You for your response.

timeSpec() on both returns 0 (Qt::LocalTime)

converting both toTimeSpec(Qt::UTC), just for a try, and comparison again failed.

However "converting" toTime_t(), actually made the test pass!

I guess both objects do hold identical time-data, but some other property keeps them away from reporting equal...
May be the way they are constructed, I dont know. I also tried manually reading from db as string and creating QDateTime, the results were the same.

Thanks, anyway
