The contents of a field, as seen by awk, can be changed within an awk program; this changes what awk perceives as the current input record. The actual input is untouched; awk never modifies the input file.

So you should redirect the output to another file and rename it back to original file if required.

pclock [options] DESCRIPTION
This manual page documents briefly the pclock command. This manual page was written for the Debian GNU/Linux distribution because the original program does not have a manual page. pclock is a program that places a small analog clock program on the desktop of X. It was designed to run under the WindowMaker window man- ager. It uses any 64x64 pixmap as a background. OPTIONS
The programs follow the usual GNU command line syntax, with long options starting with two dashes (`-') and short optoins starting with one dash. A summary of options is included below. -B PIXMAP, --background=PIXMAP Use the given pixmap as the clock background (size must be 64x64). -H COLOR, --hands-color=COLOR Draw the hands (hour, minute and second) in the specified color. -S COLOR, --second-hand-color Draw the second hand in the specified color -h, --help Show summary of options. --hour-hand-length=INT Draw the hour hand with the specified length of INT. --minute-hand-length=INT Draw the minute hand with the specified length of INT. --second-hand-length=INT Draw the second hand with the specified length of INT. --second-hand-width=INT Draw the minute hand with the specified width of INT. -s, --second-hand Don't display the second hand. -v, --version Show version of program. -w, --withdrawn Don't start up in a withdrawn (iconic) state.
