# Constant std::time::UNIX_EPOCH 1.8.0 [−] [src]

    pub const UNIX_EPOCH: SystemTime = SystemTime(time::UNIX_EPOCH)

An anchor in time which can be used to create new `SystemTime` instances or learn about where in time a `SystemTime` lies.

This constant is defined to be "1970-01-01 00:00:00 UTC" on all systems with respect to the system clock. Using `duration_since` on an existing `SystemTime` instance can tell how far away from this point in time a measurement lies, and using `UNIX_EPOCH + duration` can be used to create a `SystemTime` instance to represent another fixed point in time.

## Search Tricks

Prefix searches with a type followed by a colon (e.g. `fn:`) to restrict the search to a given type.

Accepted types are: `fn`, `mod`, `struct`, `enum`, `trait`, `type`, `macro`, and `const`.

Search functions by type signature (e.g. `vec -> usize` or `* -> vec`)
