OCIDateTimeConstruct function is not accepting timezone value

Hello team,

In our c++ source code, we are using OCIDateTimeConstruct function and we are trying to add timezone value, then the application is returning below error

The OCI function OCIDateTimeConstruct returned status -1. Error code: 1882, Error message: ORA-01882: timezone region not found.

We are passed the different timezone formats as "+08:00" or "+0800". But with both values application is throwing ORA-01882 error.

But, as per documentation, we are passing right values. Not sure, where it went wrong.
