test_precision errors if LANG is set to de_DE.UTF-8

See original GitHub issue

Description

With my native locale, test_precision.py produces an error that does not appear when LANG=C. This seems to be a problem in astropy itself (not in the test).

Expected behavior

The tests should run independently of a certain locale.

Actual behavior

___________ ERROR collecting time/tests/test_precision.py ________________________
/usr/lib/python3/dist-packages/astropy/time/tests/test_precision.py:92: in <module>

@olebole , its milestone is set for 4.0.5, which isn’t out yet. Although given the current maintainer availability, there is unlikely to be any release before 4.3. Usually a major release is also accompanied by bug fix releases of older branches.
