acknowledge past disruptions

Dear list,

I'm now using hobbit (4.2) for a few months and I really like it's possibilities, thanks for writing it!

However, one thing I've not found and answer for yet, is how to handle downtime which is in the past. The ISP where my monitoring box is located suffered a DDoS quite recently, which rendered the monitoring quite useless. I'm now looking for a way to tell hobbit "all the downtime and alerts between <timestamp> and <timestamp> can be safely ignored and should not be taken into account when generating an availability report". Is this possible?

Thanks in advance!

Wouter
