Struct Timestamp 

pub struct Timestamp {
    pub date: String,
    pub time: String,
}

The translation date, as __DATE__ and __TIME__ spell it.

Fixed for the whole translation unit, which is what the standard requires and what makes the two macros ordinary object-like macros rather than something the expander has to know about.

Fields

date: String

Mmm dd yyyy, with the day space padded, which is the format the standard fixes.

time: String

hh:mm:ss.

Implementations

impl Timestamp

pub fn now() -> Timestamp

The current time, or SOURCE_DATE_EPOCH when the build asked for a reproducible one.

Reading the environment here rather than in the driver is what GCC does, and it keeps the variable working for an embedder who never goes through a command line.

pub fn from_unix(seconds: i64) -> Timestamp

The time seconds after the epoch, in UTC.

UTC rather than local time, because a compiler whose output depends on the machine’s time zone is a compiler whose output is not reproducible.
