The server time zone value 'AEST' is unrecognized or represents more than one time zone

try to add those parameters..

jdbc:mysql://localhost:3306/fussa?useLegacyDatetimeCode=false&serverTimezone=UTC

i'm using mysql-connector-java 6.0.4

Turns out 6.x wasn't compatible, moving to 5.1.39 fixed it.

The proper solution, IMHO for AEDT, is to change the URL as follows,

jdbc:mysql://localhost:3306/sampledb?serverTimezone=Australia/Sydney
