kstat-analyzer DeprecationWarning: datetime.datetime.utcnow()

[stevecs]

just updated one of my zfs servers to ubuntu 24.04

uname -a

Linux loki 6.8.0-53-generic #55-Ubuntu SMP PREEMPT_DYNAMIC Fri Jan 17 15:37:52 UTC 2025 x86_64 x86_64 x86_64 GNU/Linux

and see that with the version of python3 on the system ( python3 3.12.3-0ubuntu2 ) is throwing a deprecation warning when running the script:
