The nightly yum job is called from /etc/cron.daily/yum.cron

This file runs yum twice, once to update yum itself and then again to
update everything else. The -R parameter is used to add a random delay
so that the various mirrors aren't all clobbered at once by every Fedora
system on the Internet. The first session has an up-to-10-minute delay
and the second has an up-to-2-hour delay. So the yum session that does
most of the work will run between 0 and 130 minutes after yum.cron is
called.

yum.cron is called from cron.daily, which in turn is run
from /etc/crontab at 4:02am local time by default.

So the answer to your original question is "roughly sometime between 4am
and about 6:15am".
