It is usually only used in conversation (spoken English). We also seldom use the 24-hour system (06:15, 19:00). It is more common to use the 12-hour system (6:15 am, 7 pm or 7:00 pm). It is common to see the 24-hour system used during travel (flight or train schedules). Example : His flight will depart at 21:30 and arrive at 00:45 the next morning.
