Red Hat Linux – Configuring Time Zone and Clock Synchronization

clock-synchronizationdatelinuxredhattimezone

In order to configure the Time Zone on red hat Linux machine ( version 5 and 6 )
need to configure
the file:

/etc/sysconfig/clock

And create a symbolic link between 

/etc/localtime to /usr/share/zoneinfo/America/New_York

but /etc/sysconfig/clock also required to set the ZONE variable as the following example:

ZONE="America/New_York"

So what is the need to set the variable ZONE=America/New_York when it is very clear from the link /etc/localtime that is pointed to /usr/share/zoneinfo/**America/New_York** ?

So what is the need to set the ZONE parameter with "America/New_York" value ?

So the "correct" way to set the clock (at least prior to RHEL 7) is to edit /etc/sysconfig/clock and then run tzdata-update which will then update /etc/localtime; you've just done that step manually.
