And in the last remark. This is my carelessness and bug. The order of the expressions was violated.
Apparently I wanted to make something like that.

Code:

        if ($7 == "PM") a[1]+=12
        if (a[1] == 24) a[1] = "00"
        $5 = a[1] ":" a[2] ":" a[3]

... ... ...
Thank you for teaching, it was very informative.

Hi nezabudka,
I'm afraid the above code still doesn't work for anything that started with a[1]==12. If you start with 12 AM on a 12 hour clock you should end up with hour 00 on a 24 hour clock (the above code ends up with hour 12) and if you start with 12 PM on a 12 hour clock you should end up with hour 12 on a 24 hour clock (the above code ends up with hour 00).

If you don't like the code I suggested in post #9 or either of the suggestions I made in post #12 you could also try:

Code:

        $5 = (($7 == "PM") ? a[1] + 12 * (a[1] != 12) : (a[1] == 12) ? "00" : a[1]) ":" a[2] ":" a[3]
