Description

I am running lighttpd 1.4.6, with mod_rrdtool.

I am running 2 copies of lighttpd on different ips, different config
files, both with rrdtool going to different databases. It was all
working fine, but then the database stopped updating. The last
modified time on both .rrd files was exactly 01:01. The size was the
same as well. I wasn't sure what the deal was, so I deleted the files
and restarted the lighttpd some time later. It happened again, and I
found the cause. this was the error. :

2005-10-24 01:01:00: (mod_rrdtool.c.410) rrdtool-response: update /var/log/lighty/site1.rrd N:0:0:0
ERROR: illegal attempt to update using time 1130115661 when last update time is
1130115661 (minimum one second step)
OK u:0.00 s:0.17 r:64099.64

I looked in my crontab, and at 01:01 every day I run the command

1 1 * * * root /usr/sbin/ntpdate clock.redhat.com >/dev/null 2>&1

So my server must be running a bit fast or something by at least a second every day.
Not sure if this is a problem with rrdtool or lighttpd's implimentation.. any ideas?
Version is 1.4.6 compiled from source on debian stable. Working fine otherwise.
