Hi Rainer and Stefano

Thanks for the reply's.

I've managed to get it working by modifying the code, It will now accept 
seconds/minutes/hours/days/months and years, as well as unixtime stamps, It 
also now converts readable date/time input into unixtime stamps.

I've also got the zoom feature to work, same as cacti.

Your right, I've increased the sampling rate to match the poll time.

Thanks again for the reply's.
