Hi Alan,

Thank you for your answer. We're changing code to be compatible with
older dateutil versions: https://review.opendev.org/#/c/747057/

However, did you notice that oslo.log also claims to require
python-dateutil>=2.7.0? [1]
It's not clear whether that's really needed: it used to require 2.5.3,
but that was bumped in [2] to synchronize with lower-constraints,
which itself must have been pulled from another dependency (but I
don't know which one).
