It is correct to say “on time.” This phrase is commonly used to indicate that something is happening or being done at the arranged or correct time. It is often used to refer to punctuality or the adherence to a specific schedule.
For example, if someone is expected to arrive at a meeting at 9:00 AM and they arrive exactly at that time, we would say that they arrived “on time.” Similarly, if a train departs from a station at its scheduled time, we can say that it left “on time.” In both cases, the event occurred at the agreed-upon or expected time.
We also use “on time” when we have made prior arrangements or appointments. If we have a dentist appointment at 2:30 PM and we arrive at the dental clinic at that exact time, we can say that we arrived “on time” for our appointment.
Furthermore, “on time” can be used to describe something that happens regularly or at a fixed time each day. For example, if a TV show airs at 8:00 PM every evening and we watch it at that specific time, we can say that we watch the show “on time.”
“on time” is used to indicate adherence to a specific schedule, punctuality, or the occurrence of an event at the arranged or expected time. It is a phrase commonly used in various contexts, including appointments, meetings, transportation, and regular activities.
