Time magic can halt time for either one person or multiple people around you depending upon the strength of the spell.
Time travel has more rules. The first? You can only travel to a time you already exist in. Then the second is that you have to give up your body.
As for the old goat? His younger self pulled some of the other versions from a point in time in which they were already defeated and about to fade anyway. Since his younger self was SUPPOSED to do that, it doesn't actually interfere with the timeline.
