Graph not Viewing

[libin]

Hi,
I have installed Cacti to monitor servers. Once all configured i had changed the time zone of the server. Currently i'm not able to view data any of the graph's. I tried adding a new graph it's works normal. But its hard to add all graph's again. can you help me to sort out the problem.
