Parsing fails if milliseconds are present in copyright time

[Flomp]

As stated in the title parsing fails with the following gpx:

hhs_77yl9msjcr.gpx.txt

The reason is the
<time>2025-04-22T19:23:27.586350</time> tag in the <metadata> section. The format is not listed in

var copyrightYearLayouts = []string{
	"2006",
	"2006Z",
	"2006-07:00",
}

and thus parsing fails. However, the value is allowed by the GPX specification.

Where in the GPS specification does it state that such a format is allowed? It looks to me like

<time>2025-04-22T19:23:27.586350</time>

is missing a trailing Z character.

Note that you list the copyright year layouts, but you talk about parsing a <time> element.

<time> is defined here:
https://www.topografix.com/GPX/1/1/#type_metadataType

as xsd:dateTime, which in turn is defined as:
https://www.datypic.com/sc/xsd/t-xsd_dateTime.html

So it should be valid with or without Z.
You are absolutely correct, the code I quoted is irrelevant in this case. However, I believe the issue as a whole is still valid.

The associated error I receive is:
parsing time "2025-04-22T19:23:27.586350" as "2006-01-02T15:04:05Z07:00": cannot parse "" as "Z07:00"

Thanks for the follow-up and for the links and investigation.

#44 should fix this. Would you be able to test it?

[Flomp]

Just tested it with the file mentioned above. Works like a charm. Thanks for the quick help!

Thanks for testing. I've tagged v1.5.0 which includes this fix.
