Description
I am trying to use jiff with the following features:
jiff = { version = "0.2.23", default-features = false, features = [
"alloc",
"perf-inline",
"serde",
"tzdb-bundle-always"
] }
The intention behind this is that I do not want jiff to do any IO (read files or environment variables), and I require handling of timezones, therefore I am bundling the tzdb and implicitly setting no_std.
I am not allowed / do not want to do unnecessary syscalls.
Is this the correct way to do this? currently, this panics with:
thread 'main' (35272228) panicked at src/main.rs:161:30:
called `Result::unwrap()` on an `Err` value: failed to find time zone `America/New_York`, since there is no global time zone database configured (and is currently impossible to do so without Jiff's `std` feature enabled, if you need this functionality, please file an issue on Jiff's tracker with your use case)
(this is when constructing any civil time, such as:
// clock: jiff::civil::date(2024, 7, 4)
// .at(12, 0, 0, 0)
// .in_tz("America/New_York")
// .unwrap(),
)
Thank you.
