The same problem occur on both v2.7 and v2.8
v2.7 build 371
v2.8 build 264

Hi,

Thanks for reporting this to us. This is very confusing, and I'm not entirely sure why this is happening. We are trying to reproduce this issue (by manually changing our timezone). We'll let you know once we have any updates.

Hi,

When this issue next occurs could you paste the following into your browser:

http://finance.yahoo.com/d/quotes.csv?S=EURUSD%3DX&f=snd1t1l1yr

This will download the equivalent data as a CSV file. Could you then check whether the data here is correct.

Hello Chris,

Sorry for delay update.
I noticed that the date will be shifted (to next day) when it is after 7am (BKK time: GMT+7).
Ex: Bkk time - 12 Sep 2012 10:02 AM
- Yahoo website: 11 Sep 2012 11:02 PM
- Yahoo quotes (from your link): 12 Sep 2012 11:02 pm

I captured the screenshot from yahoo website and Omniscope file here.
Please find the attached files.

Hi,

Is the CSV data shifted too or is it only in Omniscope?

Yes, the data in csv is shifted too.

Hi,

Ok so it appears that yahoo is automatically shifting the date, but not the time, based on your location. It is slightly strange that they are not shifting the time as well, since this gives an incorrect value.

We will investigate this further, but in the meantime you could compensate for this discrepancy adding a new formula field which would change the date back to the correct value.
