I have confirmed that I have the correct subscription level for historical data access within IB, yet I am getting the following error in TWS and IBGateway when the script attempts to retrieve price history:

18:19:39:097 <- 20-6-11-0-JNPR-STK--0---SMART-ISLAND-USD---0-20221201 07:19:39 GMT-1 day-103 D-1-ASK-2--
18:19:39:509 -> 4-2-11-10314-End Date/Time: The date, time, or time-zone entered is invalid. The correct format is yyyymmdd hh:mm:ss xx/xxx

It appears that Zorro sends "GMT-1" for the time-zone where as IB is expecting "US/Eastern" or similar format.

Any advice on how to resolve ?
