Look here:

You tell me what is the most interesting information here, the
"descriptive information", or the "related timestamp"? In many cases,
and for many people, it's not one or the other, but _both_.
But we're repeating ourselfs. I see no new arguments. Let's stop here.
Best regards,
Wolfgang Denk
