PR Summary

This small PR resolves the datetime library warnings:

DeprecationWarning: datetime.datetime.utcnow() is deprecated and scheduled for removal in a future version. Use timezone-aware objects to represent datetimes in UTC: datetime.datetime.now(datetime.UTC). or datetime.datetime.utcnow()

Note that .replace(tzinfo=None) allows to keep the original behavior where the time appears as a naive UTC timestamp (i.e., without any timezone offset). Comparision:

# With .utcnow() or .now(datetime.timezone.utc).replace(tzinfo=None)
Time,Idle
