Do you say in time or on time?

7 Answers. "In time" usually has an implicit "for (some event)", whereas "on time" means "before some deadline". The "event" could be a deadline, but in that case "on time" is much more common. "I got there in time" - meaning "in time for some event which is assumed to be known".

Is it just in time or just on time?

Just in time means that something happened just before it would haved been too late, e.g. "His arrival was just in time to catch the train before it departed." Just on time refers to an occurrence exactly on schedule, but not earlier or later, e.g. "The train departed just on time at exactly 9:00 AM."
