It doesnt matter...
Cathay make an 'allowance' for military time. They know that military pilots (fast-jet) have less total flight time in their careers. They also know that they fly more sorties to get those hours.
They also know that military logbooks are certified correct every month!
I added the 0.2 correction to my 1st application....then quite frankly couldnt be bothered working it out.
In my interview my hours summary was less than the initial application!! I explained the discrepancy and was told "dont bother, we are aware of military time and make allowances for it."
The chap also passed comment that "rounding up" and "thick pencilling" of civil logbooks was not unknown and that they looked carefully at peoples age, background & employer vs the hours they claimed to have.
I assumed my interviewer was ex-military...in fact he was not.
He mentioned 2 nationalities in particular that they were weary of but I see no need to mention them here! I only add the comment to emphasise that Cathay are aware of some of the quality vs quantity issues involved in precise logging of flight-time.
