Control time field

I copy events with a control app.
onLoad I read the entry. onValidateSuccess I copy the entries. That worked perfectly. This no longer works since SC 9.6.006 (last update). There is a problem with the time field. For test purposes, I have adapted the control app so that it only shows me the results on the monitor. You can see that the content of the time field changes from onLoad to onValidateSuccess (something with unknown year). As I said, only since 9.6.006.

You have not written anything in the change log that anything has changed in the time field.

I hate such hidden built-in errors that suddenly disrupt entire processes. I can not understand this.

Someone is building a lot of shit here, this has to stop at last!!
