Struct Timestamp 

pub struct Timestamp(pub i64);

A Daml Timestamp — microseconds since the Unix epoch (UTC).

Convert to and from time::OffsetDateTime rather than doing epoch arithmetic by hand:

use canton_daml::Timestamp;
use time::macros::datetime;

let at = Timestamp::from_datetime(datetime!(2026-07-31 12:00 UTC)).unwrap();
assert_eq!(at.to_datetime().unwrap().year(), 2026);

Implementations

impl Timestamp

pub fn micros(self) -> i64

Microseconds since the Unix epoch.

pub fn to_datetime(self) -> Option<OffsetDateTime>

The instant as a UTC date-time, or None when the microsecond count is outside the range time can represent.

pub fn from_datetime(at: OffsetDateTime) -> Option<Self>

The timestamp for a date-time, truncated toward the past (so sub-microsecond digits never move an instant forward), or None when the instant is outside the microsecond range a Daml Timestamp can hold. Never saturates: a silent clamp would turn an out-of-range instant into a plausible-looking wrong one.
