Editing Job Listing breaks if Listing Duration is set too large.

[dericleeyy]

Describe the bug When the listing duration in Settings > Job Manager is set too large, such as 4500000000000000000 days, the job editor will no longer work. Editing Product Package will also break, if WC Paid Listing is used.

This fatal error occurs:

Ein Fehler vom Typ E_ERROR wurde in der Zeile 1493 der Datei /var/www/clients/client1/web66/web/wp-content/plugins/wp-job-manager/wp-job-manager-functions.php verursacht.

Stack trace:
