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]

oclock

OCLOCK(1)						      General Commands Manual							 OCLOCK(1)

NAME

       oclock - round X clock

SYNOPSIS

       oclock [-option ... ]

DESCRIPTION

       Oclock simply displays the current time on an analog display.

OPTIONS

       -fg color
	       choose a different color for the both hands and the jewel of the clock

       -bg color
	       choose a different color for the background.

       -jewel color
	       choose a different color for the jewel on the clock.

       -minute color
	       choose a different color for the minute hand of the clock.

       -hour color
	       choose a different color for the hour hand of the clock.

       -backing { WhenMapped Always NotUseful }
	       selects an appropriate level of backing store.

       -geometry geometry
	       define the initial window geometry; see X(7x).

       -display display
	       specify the display to use; see X(7x).

       -bd color
	       choose a different color for the window border.

       -bw width
	       choose  a  different width for the window border.  As the Clock widget changes its border around quite a bit, this is most usefully
	       set to zero.

       -shape  causes the clock to use the Shape extension to create an oval window.  This is the default unless the shapeWindow resource  is  set
	       to false.

       -noshape
	       causes the clock to not reshape itself and ancestors to exactly fit the outline of the clock.

       -transparent
	       causes the clock to consist only of the jewel, the hands, and the border.

COLORS

       If you would like your clock to be viewable in color, include the following in the #ifdef COLOR section you read with xrdb:

       *customization:		       -color

       This  will  cause  oclock  to pick up the colors in the app-defaults color customization file: /usr/X11R6/lib/X11/app-defaults/Clock-color.
       Below are the default colors:

       Clock*Background: grey
       Clock*BorderColor: light blue
       Clock*hour: yellow
       Clock*jewel: yellow
       Clock*minute: yellow
