How Does the Military, Police, Etc. Notate the "second" 1:30 am when we "fall back"?

How do places where precise timekeeping is essential handle the repeat of an hour when we go off Daylight Savings Time?

There are certain professions in which I imagine very specific denotation of time is particularly important — hospital, military, first-responders (police, fire, ambulance), specialized equipment, etc.
"Spring forward" is probably not a problem, because it "removes" an hour — 2:00 jumps to 3:00. But in the fall, an hour is repeated — that's what I'm curious about.
In these venues, how do they handle properly distinguishing the first 1:30 am from the second 1:30 am? Is it done informally (i.e. Joe the ambulance driver writes down "1:30 am (second time 'round)" in his log while Frank the ambulance driver writes down "1:30 am post-DST" and George the ambulance driver forgets and just writes down "1:30 am"? Or is there a generalized standard in the field.
