stratadb / isValidTimestamp

Function: isValidTimestamp()

function isValidTimestamp(value): value is number;

Defined in: src/timestamps.ts:233

Type guard to check if a value is a valid timestamp.

Parameters

value

unknown

Value to check

Returns

value is number

True if value is a valid timestamp number

Remarks

A valid timestamp is a positive number that represents a reasonable date. This function checks if the value is a number and falls within a plausible range (after 1970 and before year 3000).

Example

const input: unknown = getUserInput();

if (isValidTimestamp(input)) {
  // TypeScript now knows input is a number
  const date = timestampToDate(input);
  console.log(date.toISOString());
} else {
  throw new Error('Invalid timestamp provided');
}
