One option is to use touch to create a temporary file with the same timestamp as the original file, then use that to re-touch the original file once you have made your change.
Code:
$ touch -r file1 file1.tmp
$ ll file1*
-rw-r--r-- 1 scott staff 35 27 Nov 07:45 file1
-rw-r--r-- 1 scott staff 0 27 Nov 07:45 file1.tmp
$ vi file1
$ ll file1*
-rw-r--r-- 1 scott staff 36 17 Dec 18:50 file1
-rw-r--r-- 1 scott staff 0 27 Nov 07:45 file1.tmp
$ touch -r file1.tmp file1
$ ll file1*
-rw-r--r-- 1 scott staff 36 27 Nov 07:45 file1
-rw-r--r-- 1 scott staff 0 27 Nov 07:45 file1.tmp

diff3
DIFF3(1) General Commands Manual DIFF3(1)NAME
diff3 - 3-way differential file comparison
SYNOPSIS
diff3 [ -ex3 ] file1 file2 file3
DESCRIPTION
Diff3 compares three versions of a file, and publishes disagreeing ranges of text flagged with these codes:
==== all three files differ
====1 file1 is different
====2 file2 is different
====3 file3 is different
The type of change suffered in converting a given range of a given file to some other is indicated in one of these ways:
f : n1 a Text is to be appended after line number n1 in file f, where f = 1, 2, or 3.
f : n1 , n2 c Text is to be changed in the range line n1 to line n2. If n1 = n2, the range may be abbreviated to n1.
The original contents of the range follows immediately after a c indication. When the contents of two files are identical, the contents of
the lower-numbered file is suppressed.
Under the -e option, diff3 publishes a script for the editor ed that will incorporate into file1 all changes between file2 and file3, i.e.
the changes that normally would be flagged ==== and ====3. Option -x (-3) produces a script to incorporate only changes flagged ====
(====3). The following command will apply the resulting script to `file1'.
(cat script; echo '1,$p') | ed - file1
FILES
/tmp/d3?????
/usr/lib/diff3
SEE ALSO diff(1)BUGS
Text lines that consist of a single `.' will defeat -e.
Files longer than 64K bytes won't work.
