Subject: [PATCH] Parse /etc/localtime by DateTime::TimeZone::Tzfile
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit
If there is valid /etc/localtime, then the system has configured local
time. If the file is not a symlink to /usr/share/zoneinfo or a copy
from there, then it's still a valid configuration. The only issue is
one cannot know the time zone name (Unfortunately, the time zone
abbreviations are ambiguous.)
This patch implements this scenario and caused returning
a DateTime::TimeZone::Tzfile object instead of dying with
"Cannot determine local time zone" message.
