When using 24-hour time, I know how to pronounce most times: 01:34 is
"(oh) one thirty-four," 14:00 is "fourteen hundred," and 22:06 is
"twenty-two oh six."

Times from the first hour of the day are a little more tricky. Is
there a standard way to pronounce times from 00:00 to 00:59?

Dear nsevs-ga,

If you wish to be strict in your use of the 24 hour clock to avoid any
confusion, each individual number should be clearly pronounced. O
should be pronounced as Zero. So, 00:01 is zero zero zero one. 00:15
is zero zero one five. In radio communications, this method is used
throughout the whole of the 24 hours.

Away from radio communications there is then divergence. Personally, I
use zero, but I was trained in radio communications. I know that Oh is
sometimes used instead of zero by ?civilians?. I have discovered that
the US coastguard refers to ?zero, zero, fifteen.? and as you?ve
observed, there is fourteen hundred, fourteen thirty six, etc. etc.

So, strictly it should be pronounced by individual numbers, but in
practise there is quite a wide variation.
