Simple steps to update change modify timezone in linux
There are several different ways to manage time in Linux. This quick tip will show you how to quickly change the local time to the correct time zone for the server. In this Linux tip I’ll show you how to change the localtime to your (or a) current time zone.Location of the local time file
Linux looks at "/etc/localtime" to determine the current time of your machine. This can either be a symbolic link to the correct time zone or a direct copy of the time zone file.
Timezone files are located in "/usr/share/zoninfo/"
I change the Linux time zone by copying or making a symbolic link to from /usr/share/zoneinfo/America/Chicago to /etc/localtime
By two methods we can change Time Zone in linux RHEL 7 or RHEL 8
Method - 1
