When I use IEM to do patching in my redhat servers. It will auto update client’s time zone from GMT (orginal) -> CST.
I tried to use “yum update” in another client instead of IEM fixlet. And did not happen this problem. So I think it is because IEM/fixlet included some conditions to update the timezone file.
This is the first I’ve heard of this issue. We just perform patches; we don’t do anything with timezone. I just tested it and I didn’t see the problem you described. Out of curiosity, which RHEL site are you using, since we have multiple.
Does this happen with every fixlet or any specific one? If so can you share the fixlet ID?
And you mentioned you tried yum update on another client you don’t see the problem. How about trying yum update on the machine where you see the timezone change?
