Luxon invalid date

Question

I'm using Luxon 3.3.0 and trying to parse this date.

const dateStr = '09-MAY-23 01.53.41.500211 PM';

const dateTime = DateTime.fromFormat(dateStr, 'dd-MMM-yy hh.mm.ss.SSSSSS a');

console.log(dateTime );

But I get an invalid date. Any ideas to why that would happen?

Here is the jsfiddle. https://jsfiddle.net/bnv7uw3t/2/

Answer 1

Problem in your code is that SSSSSS is not a valid format specifier.

Upon closer inspection of the sources while DateTime objects only support up to milliseconds it is possible to parse your input with u specifier which, contrary to the docs accepts up to 9 digits (discarding part after first 3).

const dateStr = '09-MAY-23 01.53.41.503211 PM';
const dateTime = DateTime.fromFormat(dateStr, 'dd-MMM-yy hh.mm.ss.u a');
console.log(dateTime);
