Account Job Posting Alerts

Navigate to Account Alerts page and we'll show you 

The date shown in our Job Posting Alerts indicates when the job was first posted on LinkedIn.

Though LinkedIn job postings do automatically expire after a certain period of time and when that happens, recruiters need to constantly re-post the job. When the job is re-posted on LinkedIn, it updates the time stamp to 'posted 3 days ago' on LinkedIn.
