getCreationDate has issues parsing some dates

[saul-prepared]

What were you trying to do?

Trying to get the creation date of a PDF. The PDF has a creation date of D:20210514143134-5'00'

How did you attempt to do it?

Call the getCreationDate function.

const data = new Uint8Array(doc.Body as Buffer);
const pdfDoc = await PDFDocument.load(data, {
updateMetadata: false
})
let originalCreateDate = moment(pdfDoc.getCreationDate()).utc().toDate();

What actually happened?

It throws the following error "Attempted to convert "D:20210514143134-5'00'" to a date, but it does not match the PDF date string format."

What did you expect to happen?

Expected it to return a date.

How can we reproduce the issue?

Here is the link to the JS fiddle https://jsfiddle.net/3fu4vj2c/1/
The example is the copied and pasted parseDate function.
I cannot provide the pdf file that caused the issue because it is a legal document that cannot be shared.

The JS Fiddle has a suggested fix as well.

Hi there!

Have the same issue with : "D:20241108090416-04'00''"

Found where the error is for you @saul-prepared :

/^D:(\d\d\d\d)(\d\d)?(\d\d)?(\d\d)?(\d\d)?(\d\d)?([+-Z])?(\d\d)?'?(\d\d)?'?$/
regex does not match your date

Could be nice to fix this error as other softwares does handle them.

/^D:(\d\d\d\d)(\d\d)?(\d\d)?(\d\d)?(\d\d)?(\d\d)?([+-Z])?(\d?\d)?'?(\d\d)?'?'?$/
solves the issue, but your date is not a valid JS Date, so maybe you should modify the function too, to add automatically a 0 if none was provided.
