Marciej, I went the HDBC route and got the same problem. Although it does not seem to be officially blessed, try installing the time-1.1.3 package. It's working for me at least, which I know is a dubious recommendation.
Also, I am currently using the hdbc-odbc package for accessing MySQL. I couldn't get hdbc-mysql to work properly. I hope that once I get this project working right, I'll have a chance to dig into the hdbc-mysql issue itself. Good luck!
