TimestampMicros

Struct TimestampMicros 

Source
pub struct TimestampMicros(/* private fields */);
Expand description

A i64 timestamp expressed as microseconds since the UNIX epoch (UTC).

§Examples

use questdb::ingress::TimestampMicros;

let ts = TimestampMicros::now();

or

use questdb::ingress::TimestampMicros;

let ts = TimestampMicros::new(1695312859886554);

or

use questdb::ingress::TimestampMicros;

let ts = TimestampMicros::from_systemtime(std::time::SystemTime::now())?;

or

use questdb::ingress::TimestampMicros;

#[cfg(feature = "chrono-timestamp")]
let ts = TimestampMicros::from_datetime(chrono::Utc::now());
