I came back to a previously working local server that accesses a remote datasource. I have no clue what changed in the interim, but when I try to run my local scripts that contain calls to the datasource, or when I try to create a new CF datasource to access the server db, I get this error text. I don't know where to go to change time zone values. I did see a page on stackoverflow that described how to access the CF server's JVM arguments to insert "-Duser.timezone=" and then your timezone ID. This did not work.
I should note that the template that makes calls to this db on the live server works just fine.
CDT is not a valid timezone, its just a name for an American zone when in DST. Timezones are usually defined as something like America/Chicago, which gives you CST and follows DST. If you don't need to follow DST then use Etc/GMT+6 for CST. There is a database of Timezones with details in places like https://en.wikipedia.org/wiki/List_of_tz_database_time_zones
I wouldn't set the time-zone as a global JVM property. If you did, it would be taken up by software components that didn't need the time-zone.
You should set the time-zone as a property of the specific datasource. To do so, proceed as follows:
1) Open the ColdFusion Administrator and go to the Data Sources page.
2) Click on the button to edit the datasource in question (OleSouth), then on the button Show Advanced Settings.
3) Enter your time-zone in the Connection String field as:
Obtain the value time_zone_of_your_database_server from the column "TZ database name" in https://en.wikipedia.org/wiki/List_of_tz_database_time_zones
Mine, for example, is Europe/Amsterdam. Hence:
4) Press the button to Submit the change.
