Webreports last report time one hour before

Hi,
Our webreports client’s “last report time” one hour before from console. So Scheduled reports coming 1 hour later from now. How can we fix this problem ? Server and db’s time is true.

New update ;
Explorer is ok but chrome is not . When i create scheduled report from ie, report is coming right time .

Probably I’m wrong, but talking about web reports, a difference of right 1h, this remember me the feature about DST documented at this link ->

https://www-03preprod.ibm.com/support/knowledgecenter/SSQL82_9.5.0/com.ibm.bigfix.doc/Platform/Config/c_webreport_dst.html

But sounds strange to me there’s a difference depending the browser … is it possible there are in one of the two browsers cached information make the difference?

It is strange but true. I editted scheduled task with ie (created from chrome) , now it is running right time.
