Say the first two digits, then the last two, then "hours." 1730 is "seventeen thirty hours." On the hour, say "hundred": 0800 is "zero eight hundred hours." Before 1000, say the leading zero.
What is Zulu time?
Zulu time is Coordinated Universal Time (UTC), the time at zero degrees longitude with no daylight saving. The military and aviation use it so everyone works from one clock. Z is the letter for the zone, and Zulu is its NATO phonetic name.
Is it 2400 or 0000?
Use 0000 for midnight at the start of a day. 2400 is sometimes written to mark the very end of a day, like a shift that ends at 2400, but clocks roll from 2359 to 0000.
