Summary of problem

When using python 3.12 and ddtrace 2.14.4 we get a deprecation warning:

/usr/src/.venv/lib/python3.12/site-packages/ddtrace/profiling/exporter/http.py:220: DeprecationWarning: datetime.datetime.utcfromtimestamp() is deprecated and scheduled for removal in a future version. Use timezone-aware objects to represent datetimes in UTC: datetime.datetime.fromtimestamp(timestamp, datetime.UTC).

This started burning through our log quota and the alternative is to add a warnings filter which is not ideal.

@joaonsantos - Thank you for reporting this! I am taking an attempt to switch it over and am getting it reviewed: #11850 .

In terms of workarounds, I can only think of filterwarnings on the Python side to filter out to datetime messages:warnings.filterwarnings('ignore', message='datetime.datetime'). Can you give some reasons why this option isn't great? I'm curious to see if there are better options to cover its limitations while we wait for the PR to be merged.

Another option that I can think of is possibly a logs exclusion filter, but this still causes the logs to hit Live Tail first. More details can be found here: https://docs.datadoghq.com/logs/log_configuration/indexes/#exclusion-filters .

See #11608 and
#11497.

Starting with [Python
3.12](https://docs.python.org/3/whatsnew/3.12.html), there were changes
to datetime:
>
[datetime](https://docs.python.org/3/library/datetime.html#module-datetime):
[datetime.datetime](https://docs.python.org/3/library/datetime.html#datetime.datetime)’s
[utcnow()](https://docs.python.org/3/library/datetime.html#datetime.datetime.utcnow)
and
[utcfromtimestamp()](https://docs.python.org/3/library/datetime.html#datetime.datetime.utcfromtimestamp)
are deprecated and will be removed in a future version. Instead, use
timezone-aware objects to represent datetimes in UTC: respectively, call
[now()](https://docs.python.org/3/library/datetime.html#datetime.datetime.now)
and
[fromtimestamp()](https://docs.python.org/3/library/datetime.html#datetime.datetime.fromtimestamp)
with the tz parameter set to
[datetime.UTC](https://docs.python.org/3/library/datetime.html#datetime.UTC).
(Contributed by Paul Ganssle in
[gh-103857](python/cpython#103857).)

The result is that the usage of **utcnow** and **utcfromtimestamp** now
throw deprecation warnings when used, ie:
> DeprecationWarning: datetime.datetime.utcfromtimestamp() is deprecated
and scheduled for removal in a future version. Use timezone-aware
objects to represent datetimes in UTC:
datetime.datetime.fromtimestamp(timestamp, datetime.UTC).


There's a difference of `+00:00` between the old version and the new
format.

**For utcnow -> now**
- `datetime.datetime.utcnow().isoformat()` |
`'2025-01-02T19:51:32.579733'`
- `datetime.datetime.now(datetime.timezone.utc).isoformat()` |
`'2025-01-02T19:51:02.275232+00:00'`

**For utcfromtimestamp -> fromtimestamp**

Assume that `end_time_ns=1735848645000000000`:
- `(datetime.datetime.fromtimestamp(end_time_ns / 1e9,
tz=datetime.timezone.utc).replace(microsecond=0).isoformat() + "Z")`
    - returns `'2025-01-02T20:10:45+00:00Z'`
- `(datetime.datetime.utcfromtimestamp(end_time_ns /
1e9).replace(microsecond=0).isoformat() + "Z")`
    - returns `'2025-01-02T20:10:45Z'`

As a result, I attempted remove the trailing ones to be consistent with
the old format, but can bring it back.
