1:00 AM. Hours below 1200 map straight across, so 0100 is simply 1:00 in the morning. Military time never uses a colon and never uses AM or PM, because the hour alone says which half of the day you mean.

How do you say 0100?

"zero one hundred hours". Times on the hour take "hundred", so the trailing zeros are spoken rather than skipped. The leading zero is spoken as "zero", which is what distinguishes it from a twelve hour reading.
