[R-SIG-Finance] Accessing "row names" in an object created by quantmod

Colleagues,

I am just learning about quantmod and I don’t understand the behavior of xts objects.

For example:
	getSymbols("AAPL”)
Creates an object AAPL

	tail(AAPL)
yields:
           AAPL.Open AAPL.High AAPL.Low AAPL.Close AAPL.Volume AAPL.Adjusted
2017-08-31    163.64    164.52   163.48     164.00    26785100        164.00
2017-09-01    164.80    164.94   163.63     164.05    16591100        164.05
2017-09-05    163.75    164.25   160.56     162.08    29468500        162.08
2017-09-06    162.71    162.99   160.52     161.91    21651700        161.91
2017-09-07    162.09    162.24   160.36     161.26    21928500        161.26
2017-09-08    160.86    161.15   158.53     158.63    28352600        158.63

I would like to extract a row based on the date column.  The usual approaches (e.g., rownames) do not work.  

So, how do I extract the date column?

Dennis
