**nt-time** is a [Windows file time] library for [Rust].
## Usage
Add this to your `Cargo.toml`:
```toml
[dependencies]
nt-time = "0.8.1"
```
### Example
```rust
use core::time::Duration;
use nt_time::{
time::{macros::datetime, OffsetDateTime},
FileTime,
};
let ft = FileTime::NT_TIME_EPOCH;
assert_eq!(
OffsetDateTime::try_from(ft).unwrap(),
datetime!(1601-01-01 00:00 UTC)
);
let ft = ft + Duration::from_secs(11_644_473_600);
assert_eq!(
OffsetDateTime::try_from(ft).unwrap(),
OffsetDateTime::UNIX_EPOCH
);
assert_eq!(ft.to_raw(), 116_444_736_000_000_000);
assert_eq!(FileTime::new(u64::MAX), FileTime::MAX);
```
