[rrd-users] Start time with rrdtool create

[Tobias Oetiker]

Glenn

you are on the wrong track ... if rrdtool is not happy with the
time, it will complain ... my guess is that either:

a) your updates are further apart than you have defined with mrhb

b) your data is outside the limits defined for the datasource
   (upper and lower).

in both cases rrdtool will silently ignore your data ...

cheers
