Date format of Camunda BPM Run


I am trying to use Camunda BPM Run along with the OpenAPI documentation to do a quick standalone process engine with a web application.

Unfortunately, the default date-time format does not meet the OpenAPI spec of being RFC3339 compliant and as such, the client generation for Golang is broken as Golang will not parse non-compliant date-time on the default time.Time type.

I found instructions for changing web.xml to change the date format, but I’m not sure how to apply that to Camunda BPM Run. In case it’s not obvious, I’m not well versed in Java and Java application deployments (hence, Run). Any assistance would be appreciated. Thank you!
