And running this script:
------------------------------------------------------------------------------
tell application "Numbers"
if document 1 exists then
tell document 1
tell active sheet
set activeTable to (the first table whose class of selection range is range)
tell activeTable
set cellRef to first cell of selection range
tell cellRef
set cellValue to value
set cellFormattedValue to formatted value
end tell
end tell
end tell
end tell
end if
end tell
{cellValue, cellFormattedValue}
------------------------------------------------------------------------------
--> {date "Friday, October 28, 2016 at 23:03:00", "10/28/16 22:03"}
Value vs Formatted Value.
TIA.
