isValidUnixInterval

Signature

isValidUnixInterval(start: string | number, end: string | number): boolean

import { isValidUnixInterval } from "@northguild/gmt/unix/interval";

Return true if start and end form a valid Unix interval — both finite numbers

• and start <= end.
• Both inputs must be numbers (or numeric strings that coerce to finite numbers).
• Equal start === end is valid.
• Non-finite values (NaN, Infinity) return false.

Parameters

Parameter	Type	Description
start	string | number	Unix epoch value (seconds or milliseconds) — interval start
end	string | number	Unix epoch value (seconds or milliseconds) — interval end

Returns

true if start and end form a valid Unix interval, or false on invalid input

Examples

isValidUnixInterval(0, 1700000000) // true
isValidUnixInterval(1000, 1000) // true
isValidUnixInterval(1700000000, 0) // false
isValidUnixInterval("0", "1700000000") // true
