# kSecCodeInfoTimestamp

A key whose value indicates the actual signing date.

```
let kSecCodeInfoTimestamp: CFString
```

## Discussion

The value is a <doc://com.apple.documentation/documentation/CoreFoundation/CFDate> object describing the signing date as (securely) certified by a timestamp authority service. This timestamp cannot be falsified by the signer, and is trusted to the same degree as the timestamp service that created the timestamp.
