Parsing Date Inputs

const result1 = DateRangeParser.parseDateInput('now');
console.log(result1); // { start: [current timestamp], end: [current timestamp] }

const result2 = DateRangeParser.parseDateInput('today');
console.log(result2); // { start: [start of today], end: [end of today] }

const result3 = DateRangeParser.parseDateInput('now -> 6h');
console.log(result3); // { start: [current timestamp], end: [current timestamp + 6 hours] }

const result4 = DateRangeParser.parseDateInput('now -> -6h');
console.log(result4); // { start: [current timestamp - 6 hours], end: [current timestamp] }

Handling Errors

const result = DateRangeParser.parseDateInput('invalid input');
if ('error' in result) {
    console.error(result.error); // Outputs: "Unknown keyword: invalidinput"
}
