bug#4637: 23.1; (elisp)Time of Day doc

[Drew Adams]

The doc for `current-time-string', `current-time-zone', and
`float-time' says the "argument should be a list whose first two
elements are integers."
 
This says nothing about the rest of the list. Does it mean that the
rest is ignored and could be anything (any number of elements of any
types)? If so, please state that clearly.
 
Or should we rather be saying that the argument has the same form as
what is returned by either `current-time' or `file-attributes' (for a
time attribute), both of which are described in detail?
 
IOW, is it any list of at least two numbers, with the elements past #2
being ignored, or is it a list of either two or three numbers? In the
latter case, if three numbers, is the third number (microsecs) used or
ignored? This is not clear, and the doc strings do not clear it up.
 
Also, there are 4 occurrences of the term `file-attributes', but only
three of them are followed by a cross reference to node `Definition of
file-attributes'. Either all four should have the cross reference or
we should include only one cross reference for the whole node.
