Read and write military time
Flight boards and schedules say 1830 or 18:30 — convert between 24-hour, 12-hour, and compact forms.

The job
A boarding pass says 'dep 1945', a runbook says 'restart at 03:15', and a colleague writes 'half past six'. Converting between 24-hour clock, AM/PM, and the compact '1830' notation should take seconds.
Convert either way
Enter time in any of the forms — `1945`, `19:45`, `7:45 PM` — and get all three representations at once: 24-hour with colon, compact military digits, and 12-hour AM/PM.
- Leading zeros matter in compact form: 03:15 is `0315`, not `315`.
- Midnight is `0000`; 24:00 is invalid — use 00:00 of the next day.
Worked example
'Brief at 0600, wheels up 0730' reads as 6:00 AM and 7:30 AM. Reverse: 10:20 PM becomes `2220` for a NATO-style schedule.
Where it stops
Clock conversion only — no seconds, no timezone shift, no date arithmetic. For 'what time is it in Tokyo when it's 9 AM here' use the timezone converter.
