3.3.2.3.7 Using a localtime file
The localtime zone is stored in /etc/localtime and is used by the GNU library for
C (glibc) if no value is set for the TZ environment variable. This file is either
a copy of /usr/share/zoneinfo/file or a symbolic link to it. If EC300 cannot
find/usr/share/zoneinfo/file, please download from the web site you need the time
zone information file (https://www.iana.org/time-zones), and links to the local
time in the EC300 file.
Note
After successfully downloading the required time zone information file, unzip it,
and then compile and generate the corresponding binary file using zic command. The
generated time zone file is "/usr/share/zoneinfo/custom time zone filename".
