rrdtool v_1.0.45

My machine's hardware clock doesn't work and I set kernel 
time at boot with ntpd. Usually at boot the clock time is 
Jan 1970 (or something like that). Apparently in the last 
boot the clock was at 2*10^9 secs (approx), ie some time in 
the future and rrdtool started recording. Sometime later 
(don't know when) the clock got the right time (about 
1.2*10^9 secs). Now rrdtool won't write because current time 
is less than the last time.

Is there anyway to fix the rrd file?

Thanks Joe
