How to change opmanager's system time ?

How to change opmanager's system time ?

in opmanager version 9.2 . the system time is different than the server time. 

also there is no option the change time settings from web interface.

i tried to add some extra lines on wrapper.conf file and restart the service & server but it didnt work.

Note: the server regional settings are all english. 

because of that bug when we get traffic reports it shows wrong times in the report.

How to fix that situation ?

Thanks.
