Compiled zoneinfo file parsing library for Rust.
License: MIT License
This is a library for parsing compiled versions of the Olson zoneinfo database.
This crate works with Cargo. Add the following to your Cargo.toml dependencies section:
[dependencies]
datetime = "0.5"
zoneinfo_compiled = "0.5"The earliest version of Rust that this crate is tested against is Rust v1.31.0.
Hello, your project is great for tzfiles and I made some adaptations if you want them. Please let me know if you are interested and would like me to form PRs.
Causes ogham/exa#517
Way to reproduce (with master branch 2d8a832) :
use zoneinfo_compiled::CompiledData;
use datetime::TimeZone;
pub fn main() -> Result<(), Box<dyn std::error::Error>> {
TimeZone::from_file("/usr/share/zoneinfo/Asia/Muscat")?;
Ok(())
}Or manually set the current time to those and read /etc/localtime instead.
Timezone that I found failed to parse includes but not limits to UTF+3 (including Amman, Aden) and UTF+8 (including Shanghai, Hong_Kong,Macau)
Many other timezone works just fine.

MIT requires text license to be present along with sources. You would help me a lot if you could put it into repo & make new release.
Hey there,
