Your solution is functional but can I make a few suggestions to help improve it.
1. Awk can open an read files without the help of cat
2. No need to change order of the fields GNU date would accept a date in the format anyway.
3. OP requires matching on line containing "After :"
OP is only wanting to match a filedate older than 2 days, the code above would also match filedate up to 2 days in the future.
OP was already using Arithmetic Expansion to calculate differences between epoch times.
I believe $((expression)) is superior to let as its more portable and is much better than using /usr/bin/expr as this wastes resources starting a new process and loading the expr command binary into memory to execute it.
I'd simply go with:

basename
basename(1) User Commands basename(1)NAME
basename, dirname - deliver portions of path names
SYNOPSIS
/usr/bin/basename string [suffix]
/usr/xpg4/bin/basename string [suffix]
dirname string
DESCRIPTION
The basename utility deletes any prefix ending in / and the suffix (if present in string) from string, and prints the result on the stan-
dard output. It is normally used inside substitution marks (``) within shell procedures.
/usr/bin
The suffix is a pattern defined on the expr(1) manual page.
/usr/xpg4/bin
The suffix is a string with no special significance attached to any of the characters it contains.
The dirname utility delivers all but the last level of the path name in string.
EXAMPLES
Example 1 Setting environment variables
The following example, invoked with the argument /home/sms/personal/mail sets the environment variable NAME to the file named mail and the
environment variable MYMAILPATH to the string /home/sms/personal:
example% NAME=`basename $HOME/personal/mail`
example% MYMAILPATH=`dirname $HOME/personal/mail`
Example 2 Compiling a file and moving the output
This shell procedure, invoked with the argument /usr/src/bin/cat.c, compiles the named file and moves the output to cat in the current
directory:
example% cc $1
example% mv a.out `basename $1 .c`
ENVIRONMENT VARIABLES
See environ(5) for descriptions of the following environment variables that affect the execution of basename and dirname: LANG, LC_ALL,
LC_CTYPE, LC_MESSAGES, and NLSPATH.
EXIT STATUS
The following exit values are returned:
0 Successful completion.
>0 An error occurred.
