crazy timestamp bug in feather? #351
Comments
Can you report in Apache Arrow? Someone will need to investigate once we get R fully moved over from this codebase |
hi wes you mean on the JIRA? can you send me the link? thx! |
done |
Thanks. It will need a more descriptive / objective title |
like "INSANE timestamp ERROR - win 400$ click here" I guess |
We have hundreds of issues. We need to be able to understand the nature of the problem from the title |
sure i was kidding :) |
monsieur @wesm , do we have an update about this bug? timestamps are always tricky... thanks!! |
I'm not sure the status, what does the JIRA issue you created say? |
what do you thik, @wesm ? when is .13 being released? Thanks! |
Please comment on ARROW-3543. I estimate timeline for 0.13 to be end of March |
Hello the dream team,
Thanks for this wonderful package. I was playing with feather and some timestamps and I noticed some dangerous behavior. Maybe it is a bug.
Consider this
Here I create the corresponding
EST
timestamp of my original timestamps (inUTC
time).Now saving the dataframe to
csv
or tofeather
will generate two completely different results.Switching to R.
Using the good old
csv
gives me something a bit annoying, but expected. R thinks my timezone isUTC
by default, and wrongly attached this timezone totimestamp_est
. No big deal, I can always usewith_tz
or even better: import as character and process as timestamp while in R.Now look at what happens with
feather
:My timestamps have been converted!!! pure insanity.
Am I missing something here?
Thanks!!
