What does 337 (invalid date time zone) mean on the Interactive Brokers API?

Risk warning: CFDs and spread bets are complex instruments and come with a high risk of losing money rapidly due to leverage. You can lose money on these products, and each provider publishes its own loss figure under FCA rules. You should consider whether you understand how they work and whether you can afford to take the high risk of losing your money. Automated and API trading can amplify losses through bugs, connectivity failures and runaway orders.
How do I fix 337 (invalid date time zone)?
The message gives the expected format, yyyymmdd hh:mm:ss followed by a time zone, with the date and the time zone optional. The vendor's page adds no further remedy.
