does it work to use the

parser = all_parsers

and then

parser.read_csv

pattern from the other tests in this file?

Yes, it works very well, except pyarrow. I added @xfail_pyarrow.

content = "a\n2020-01-01T00:00:00+01:00\n2020-01-01T00:00:00+00:00"
result = read_csv(StringIO(content), parse_dates=["a"])["a"]
expected = Series(
[
Timestamp("2020-01-01 00:00:00+01:00"),
Timestamp("2020-01-01 00:00:00+00:00"),
],
name="a",
index=[0, 1],
)
tm.assert_series_equal(result, expected)
