Dates not converting by locale

[barouchk]

When showing the month date like DD * YYYY and using current user locale, the locale not changed in momentjs static resource

this example is working: https://onecompiler.com/javascript/4472ruc6g

but when I'm debugging the package I found that the moment locale remains in 'en'.

not sure in the static resource is momentjs with locale

solution:
you can use: Formatted Date Time in the: timelineMonth component
like that:

<lightning-formatted-date-time value="2025-12-12" month="short" year="numeric"></lightning-formatted-date-time>
and transfer the date value as is with formatting in component: activityTimeline

line:                     monthItem.monthValue = moment(key).format("MMM  •  YYYY");
to:                     monthItem.monthValue = moment(key);

that way the visibility of the dates will run by the locale of the running user
