Hi, i´m getting this error when i try to upgrade concrete5 from 5.5.2.1 to 5.6.0.1 using the dashboard panel: "An Unexpected Error occured while upgrading: timezone (America/Argentina/ComodRivadavi) is not a known timezone"... and it´s true, cause the valid timezone is America/Argentina/ComodRivadavia, it seems the last letter "a" is lost. I looked for the error in the code and database, but the timezones in the supplementalData.xml file are ok. How can i fix it? how can i update concrete to the last version? thanx
