Part of the problem may be that, while RRDtool development has moved
on, Larrd has not kept pace. You might try using an older version,
(like 1.0.49) or modify the larrd-grapher.cgi script. One solution
(suggested here http://support.bb4.com/archive/200507/msg00126.html)
is to replace any colon characters in the date.

Cheers, Phil.
