Without it, the program just fallback to UTC. /etc/localtime and $TZ are two ways to specify timezone for programs. The program look up the later first, if it’s empty and then use /etc/localtime. In theory, $TZ has better performance because of the glibc will not look up the last modified time of /etc/localtime when every calling of localtime lookup.

There are some products can do it, such as eSIM.me, esim.5ber.com or https://github.com/estkme-group .
