This utility crate provides a single trait SystemTz which exposes the system_tz()
method allowing to get the timezone
from the operating system.
Currently supported platforms include unix, windows and wasm.
Valid timezones are represented with chrono_tz::Tz
which is the most common Rust standard, based on IANA Time Zone Database (Olson names).
On Microsoft Windows, because of its use of a special naming convention,
the method relies on WindowsZones,
a dataset maintained by the Unicode Common Locale Data Repository (CLDR),
which is downloaded and built into a static global object during compilation.
The crate provides a very basic binary callable by the command-line which will print the timezone on invokation.
Refer to the official documentation
for installing the cargo package manager, and then run the following command
from a terminal:
bash
$ cargo install system_tz
The interface doesn't require any argument.
bash
$ system_tz
