That's odd, as the tzdata package has the EST file on all the Red Hat machines I 
just now checked:

On RHEL 6.10:
$ rpm -qf /usr/share/zoneinfo/EST
tzdata-2018i-1.el6.noarch

On RHEL 7.6:
$ rpm -qf /usr/share/zoneinfo/EST
tzdata-2018i-1.el7.noarch

On Fedora 30:
$ rpm -qf /usr/share/zoneinfo/EST
tzdata-2019a-1.fc30.noarch

Perhaps your installation went haywire somehow?
