Custom RRD graphs end time

[bardelot]

When I wrote the "human readable dates" patch (*) I noticed that the end time is always repopulated with the current time, instead of the previous defined one.

status_rrd_graph.php

To change that behavior the $now variable should be replaced with $end (or apply the "human readable dates" patch)  :)
