# 🕒 nano-clock
**Ultra-fast date/time formatting for HTTP headers and system profiling.**
Written in Rust, sprinkled with inline assembly, optimized for the lowest latency possible.
---
## 🔥 Features
- Returns current date/time in `(i32, u8, u8, u8, u8, u8, u8)` tuple format
(`year, month, day, hour, minute, second, weekday`)
- Blazing-fast formatting of HTTP date headers (`Date: ... GMT`) in preallocated buffers
- Optional inline assembly (`nano_clock_asm`) for even lower latency
- Includes both `time()` (wall-clock) and `clock_gettime(CLOCK_MONOTONIC)` for monotonic measurements
- Zero allocations, no `String`, no `chrono`, no nonsense.

## 📦 Example
```rust
use nano_clock::{nano_clock, nano_http_date};
fn main() {
let (y, m, d, h, min, s, w) = nano_clock();
println!("Now: {y:04}-{m:02}-{d:02} {h:02}:{min:02}:{s:02} (weekday: {w})");
let mut buf = [0u8; 35];
unsafe {
nano_http_date(&mut buf, false);
}
println!("{}", std::str::from_utf8(&buf).unwrap());
}
