I have Centos6 at my Servers(text mode), When I stalled it I choosed my location, but date now is go back one day ago. I change it again but when I shutdown or restart my server it get the date one day ago again. How is the right way to configure date time and locations. I am working text mode, then I need commands or file to modify wit the right values.
Thanks
Try to configure NTP servers. RHEL sites seem to have a good solution for that.
