Usage

For detailed examples, please refer to the API Reference.

import { FullTime } from '@imhonglu/format';
// Parse time string
const time = FullTime.parse('00:00:00.000Z');
// { hour: 0, minute: 0, second: 0, secfrac: '.000', offset: undefined }

// Using parsed results
console.log(time.hour); // 0
console.log(time.toString()); // '00:00:00.000Z'
console.log(JSON.stringify(time)); // '"00:00:00.000Z"'

// Safe parsing with validation
const result = FullTime.safeParse('invalid');
if (result.ok) {
  console.log(result.data);
  // result.data returns parsed FullTime instance
} else {
  console.error(result.error);
  // result.error returns InvalidFullTimeError with error information
}
