TestGauge::test_time_block_decorator_with_label failure

Hi, I am running the test suite on some obscure architectures and observed a failure on alpha, with one test:

========================================================================= FAILURES =========================================================================
______________________________________________________ TestGauge.test_time_block_decorator_with_label ______________________________________________________

self = <tests.test_core.TestGauge testMethod=test_time_block_decorator_with_label>

    def test_time_block_decorator_with_label(self):
        value = self.registry.get_sample_value
        self.assertEqual(None, value('g2', {'label1': 'foo'}))
        with self.gauge_with_label.time() as metric:
            metric.labels('foo')
>       self.assertLess(0, value('g2', {'label1': 'foo'}))
E       AssertionError: 0 not less than 0.0

metric     = <prometheus_client.context_managers.Timer object at 0x20007441790>
self       = <tests.test_core.TestGauge testMethod=test_time_block_decorator_with_label>
value      = <bound method CollectorRegistry.get_sample_value of <prometheus_client.registry.CollectorRegistry object at 0x20007441310>>

tests/test_core.py:255: AssertionError

This is fully reproducible, and I tested on both python3.10 and python3.11 with same results.

Complete log: 41y0768.log

Any help on why this test could be failing? I know this is an unusual platform, so I can provide shell access to the machine in question if somebody would mind taking a look. I can also interactively debug, or test patches as needed.

Thank you!

tests/test_core.py:255 と TestGauge.test_time_block_decorator_with_label テストから始めます。Python 3.10 または 3.11 で報告された alpha プラットフォーム上の失敗を再現し、その後、完全な 41y0768.log と gauge のタイミング動作を調査します。プラットフォーム固有の原因を特定し、報告された動作を後退させることなくテストが成功すれば完了です。
