What are the accurate times to set for Cron Jobs?

Hi there,

Could someone please suggest “the most accurate time” for each one of these commands?

php /home/admin/web/domain.com/public_html/mautic/app/console mautic:segments:update
php /home/admin/web/domain.com/public_html/mautic/app/console mautic:campaigns:trigger
php /home/admin/web/domain.com/public_html/mautic/app/console mautic:emails:send
php /home/admin/web/domain.com/public_html/mautic/app/console mautic:campaigns:rebuild
php /home/admin/web/domain.com/public_html/mautic/app/console mautic:email:fetch

Please avoid this format >> 0 10 15 * * because I don’t know what it means…

This format is helpful >> 1 minute, 15 minutes, 30 minutes

Thanks a lot!
Salah
