Pronouncing military time

Are these pronounced correctly in military time? If not, how'd you pronounce them?


'0000 hours' = 'zero hundred hours'


'0001 hours' = 'zero hundred one hours'


'0010' = 'zero hundred ten hours'


'0030 hours' = 'zero hundred thirty hours'


'0425 hours' = 'oh four twenty-five hours'


Thank you.
