When I try to get a graph of 3 month (july, august, september) for our reporting, I calculate the seconds and then call chart2.php using pycurl.
july has 31 days, august has 31 days end september 30. So 92 days. Each day has 86400 seconds. So total seconds for 3 months: 7948800
So according to the documentation, I should be using this URL
https://zabbix-test.vermont24-7.com/zabbix/chart2.php?graphid=1124&stime=20130701000000&period=7948800

But when I view the graph, it displayes that the graphs is 3 months and 2 days long. So it probably assumes all 3 months have 30 days?

I'm using version 2.0.6 but it is not selectable.
