tiempo

isSameNanosecond

Check if two datetimes are in the same nanosecond

Returns true if both datetimes are in the same nanosecond. This is the highest precision comparison available.

Signature

function isSameNanosecond(
  date1: Temporal.Instant | Temporal.ZonedDateTime,
  date2: Temporal.Instant | Temporal.ZonedDateTime
): boolean

Example

import { isSameNanosecond } from '@gobrand/tiempo';

const time1 = Temporal.ZonedDateTime.from('2025-01-20T15:30:45.123456789Z[UTC]');
const time2 = Temporal.ZonedDateTime.from('2025-01-20T15:30:45.123456789Z[UTC]');
const time3 = Temporal.ZonedDateTime.from('2025-01-20T15:30:45.123456790Z[UTC]');

isSameNanosecond(time1, time2); // true (exact match)
isSameNanosecond(time1, time3); // false (different nanosecond)

isSameMicrosecond

Check if two datetimes are in the same microsecond

isPlainDateBefore

Check if a PlainDate is before another PlainDate
