Derive task instance execution timestamp in custom operator?

[Georg Walther <ge...@markovian.com>]

Hi all,


we wrote a couple of custom operator classes that log themselves to a
separate metadata database.
At present each task instance will log itself to this database identifying
itself with "self.task_id". Is there a way to access the execution
timestamp to amend self.task_id with?


Thank you,

Georg
