+# filetime
+
+[Documentation](https://docs.rs/filetime)
+
+A helper library for inspecting and setting the various timestamps of files in Rust. This
+library takes into account cross-platform differences in terms of where the
+timestamps are located, what they are called, and how to convert them into a
+platform-independent representation.
+
+```toml
+# Cargo.toml
+[dependencies]
+filetime = "0.2"
+```
+
+# Advantages over using `std::fs::Metadata`
+
+This library includes the ability to set this data, which std does not.
+
+This library, when built with `RUSTFLAGS=--cfg emulate_second_only_system` set, will return all times rounded down to the second. This emulates the behavior of some file systems, mostly [HFS](https://en.wikipedia.org/wiki/HFS_Plus), allowing debugging on other hardware.
