[rrd-users] week/month/year graphs showing false values

[Torsten Puls]

Hello everybody,

I use the skript below to create graphs from the mailgraph prog.
Background, I can't use CGI.
It works good. Now I've tried to create graphs for a week, month
and year. I changed --start=-86400 to -604800 (-2592000, -31536000).
But it isn't enough. The graphs showing false values. So what's wrong?
