Different timezone in WebLogic Logs and on OS

Check the time using the below commands,

date
hwclock
If this is as expected then check below

hwclock --localtime


If this is incorrect then synchronise using below command, (with root)

 hwclock --systohc --localtime



 https://access.redhat.com/documentation/en-us/red_hat_enterprise_linux/7/html/system_administrators_guide/sect-configuring_the_date_and_time-hwclock



 or you add the below startup parameter in weblogic,

 -Duser.timezone=GMT

 but I think it is OS related issue so better you resolve it on OS.
