Graphs not working correctly

[tbenoit]

When I view the "Latest Data" of a host, I click the "Graph" link to take me to the graph of that data. Unfortunately, if the graph time is set to less than 24hrs, the graph is empty. But, when set to 24hrs, I get a graph of the data.

Zabbix Version: 1.1.4

Any thoughts of where we might have a configuration issue with this one?

Check Time

First thing that comes to mind is to check the times on all the servers and computers involved, and make sure they're in sync or really close to being the same.

They all look to be within several seconds of each other except 1 server which looks to be about 2-3 minutes slower.

When I try to view the graph of the Zabbix Server itself (since it's monitoring itself) I get the same results. When I go out to "24 hrs" I see a graph, but anything lower (1, 4, 8, 12hrs) there is nothing displayed.
