Using =GoogleFinance("EURUSD","price",StartDate,EndDate)
produces two columns of results:
The date and the currency rate on that date. Great! Except that it's unclear what timezone it is using.
I tried changing the timezone of the sheet (File -> Spreadsheet settings)
but when I re-ran the formula the data did not change at all. ie. with the spreadsheet set to London time it says EURUSD
closed at 1.17093 on the 23rd May 2018 at 23:58.
But when I change the spreadsheet to New York time and re-ran the formula it still says EURUSD
closed at 1.17093 on the 23rd May 2018 at 23:58.
So if the date/time is independent of the sheet settings, then what timezone is it using?
