What is the correct format write the time in European format?

In European format, time is typically written using the 24-hour clock system. For example, 3:00 PM is expressed as 15:00. When specifying minutes, it is presented as HH:MM, such as 18:45 for 6:45 PM. Additionally, it is common to separate hours and minutes with a colon and avoid using "AM" or "PM."
