[hobbit] Time Issue

[Richard Leon]

To change my status back to normal I disabled everything for a 10 minute
time limit.
Now my unchanged status shows normal.

I had a similar issue when running the hobbit server on a VMware 
instance once.  The OS under VMWare doesn't accurately keep time - 
sometimes the time would shift backwards or forwards.  When this happens 
Hobbit does not record the data, because RRD files are time sensitive in 
that they will only accept updates within a specific time interval.

As for your problem I suspect that the system time on your server 
changed due to the different NTP server. Perhaps it was wrong before and 
now it's right, or maybe it was right before and now it's wrong.  Either 
way the jump in time is what caused the problem. I'm not sure how you 
can fix it, short of manually editing the timestamps in the rrd files.  
Maybe someone else has a better suggestion :)
