Hum, it shouldn't timeout except occasionally. They run fine for me on a
MacBook Air with Cassandra installed locally. Your machine isn't swapping is
it (free -m)?
The method datate_time_from_timestamp is indeed imported from the driver and
used exactly one. Are you suggesting there is a better replacement?
ret_dt = datetime_from_timestamp(seconds) +
datetime.timedelta(microseconds=microseconds)

> Key: CASSANDRA-18879
> URL: https://issues.apache.org/jira/browse/CASSANDRA-18879
> Project: Cassandra
> Issue Type: Improvement
> Components: CQL/Interpreter
> Reporter: Brad Schoening
> Assignee: Arun Ganesh
> Priority: Low
>
> Python 3.x introduced many updates to datetime conversion which allows
> simplified conversions.
> 1. For example, tracing.py defines a function datetime_from_utc_to_local()
> but datetime now has a native function astimezone() which will convert UTC to
> local time.
> Review the following users of datetime which apply conversions:
> * cqlshmain.py
> * formatting.py
> * tracing.py
> Example:
> {code:java}
> >>> a = datetime.datetime.now().astimezone(tz.tzutc())
> >>> a
> datetime.datetime(2023, 9, 25, 11, 22, 36, 251705, tzinfo=tzutc())
> >>> b = a.astimezone()
> >>> b
> datetime.datetime(2023, 9, 25, 14, 22, 36, 251705,
> tzinfo=datetime.timezone(datetime.timedelta(seconds=10800), 'EEST')) {code}
> See [PEP 495|https://peps.python.org/pep-0495/]
