Feature-Request: Timestamp or some other correlationID required

I am failing with the migration and since of really to few details and also what time the thread was started it seems not to be solvable.

@anon29869905 any updates on the correlationID (e.g. a timestamp on requests or even better a uuid on OTRS log and zammad-migrator log) to track down my issues?
Maybe also something of these related issues? Are multiple runs of OTRS migrator possible - maybe with yearly migrate runs? - #3 by xeno

e.g. I am often failing on:

since I cannot correlate the error with OTRS log I am failing to track down the issue
