[jira] [Commented] (ARROW-13662) [CI] Failing test
test_extract_datetime_components with pandas 0.24
[ https://issues.apache.org/jira/browse/ARROW-13662?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=17401105#comment-17401105 ]
Joris Van den Bossche commented on ARROW-13662:
-----------------------------------------------
The bug in pandas was a difference in extracting the year from Index vs Series:
{code}
In [1]: pd.to_datetime(["1970-01-01T00:00:59.123456789"]).tz_localize("UTC").tz_convert("US/Central").year
Out[1]: Int64Index([1969], dtype='int64')
In [2]: pd.to_datetime(["1970-01-01T00:00:59.123456789"]).tz_localize("UTC").tz_convert("US/Central").to_series().dt.year
Out[2]:
1969-12-31 18:00:59.123456789-06:00 1970
dtype: int64
{code}
Fixed in pandas 1.0+ (we are using pandas as "reference" to compare the result with)
