{"comment":{"created_at":"2011-10-12T18:54:16Z","body":"Again, tragic to break APIs but changing to `parse_dates=False` and `index_col=None` by default makes the most sense. I'll make sure to sound the alarm at next release time so that users review their usage of read_csv / read_table. Could use more unit testing on this-- also need to update the sphinx docs to reflect the new defaults and to document usage with MultiIndex (e.g. `index_col=[0, 1]`)-- if you get some energy feel free to do so. I'll create a separate ticket about updating the docs","updated_at":"2011-10-12T18:54:16Z","url":"https://api.github.com/repos/wesm/pandas/issues/comments/2382972","id":2382972,"user":{"avatar_url":"https://secure.gravatar.com/avatar/2c08a3eed709a9d1a2654cea45aa466f?d=https://a248.e.akamai.net/assets.github.com%2Fimages%2Fgravatars%2Fgravatar-140.png","url":"https://api.github.com/users/wesm","id":329591,"login":"wesm"}},"action":"created","issue":{"number":225,"created_at":"2011-10-12T14:19:49Z","pull_request":{"diff_url":null,"patch_url":null,"html_url":null},"body":"I loaded a dataset with an index column going from 1 to 304. Then I try to get the repr of the dataframe, but it raises `ValueError: year=100 is before 1900; the datetime strftime() methods require year >= 1900`. Looking at `df.index` shows that the numeric indices have been transformed into datetimes (the first 31 to days of this month, 32-60 as years 20xx, 61-99 as years 19xx, and higher numbers as a raw year).","comments":4,"title":"read_csv interprets index column as dates","updated_at":"2011-10-12T18:54:16Z","url":"https://api.github.com/repos/wesm/pandas/issues/225","id":1887760,"assignee":null,"milestone":{"number":6,"created_at":"2011-10-10T01:38:02Z","due_on":"2011-10-31T07:00:00Z","title":"0.4.4 minor release","creator":{"avatar_url":"https://secure.gravatar.com/avatar/2c08a3eed709a9d1a2654cea45aa466f?d=https://a248.e.akamai.net/assets.github.com%2Fimages%2Fgravatars%2Fgravatar-140.png","url":"https://api.github.com/users/wesm","id":329591,"login":"wesm"},"url":"https://api.github.com/repos/wesm/pandas/milestones/6","open_issues":1,"closed_issues":5,"description":"","state":"open"},"closed_at":"2011-10-12T18:54:16Z","user":{"avatar_url":"https://secure.gravatar.com/avatar/7f1ae3f14fd5b87c2c3f7b36014e185c?d=https://a248.e.akamai.net/assets.github.com%2Fimages%2Fgravatars%2Fgravatar-140.png","url":"https://api.github.com/users/takluyver","id":327925,"login":"takluyver"},"html_url":"https://github.com/wesm/pandas/issues/225","labels":[{"name":"Bug","url":"https://api.github.com/repos/wesm/pandas/labels/Bug","color":"e10c02"}],"state":"closed"},"legacy":{"issue_id":1887760,"comment_id":2382972}}
