You could try something like:
Code:
awk '
FNR == 1 {   
        f[++fc] = FILENAME
        if(w[fc] < length(FILENAME)) w[fc] = length(FILENAME)
}
FNR == NR {
        d[++lc] = $1
        t[lc] = $2
}
{       v[fc,$1,$2] = $3
        if(w[fc] < length($3)) w[fc] = length($3)
}
END {   printf("    Date  Time")
        for(j = 1; j <= fc; j++)
                printf("%*s%s", w[j] + 1, f[j], j == fc ? "\n" : "")
        for(i = 1; i <= lc; i++) {
                printf("%s%6s", d[i], t[i])
                for(j = 1; j <= fc; j++)
                        printf("%*d%s", w[j] + 1, v[j, d[i], t[i]],
                                j == fc ? "\n" : "")
        }
}' FILE[12]

If you are running on a Solaris/SunOS system, use /usr/xpg4/bin/awk or nawk instead of awk.

Note that this script will work for two or more files, but the 1st file given must include all date/time pairs that you want to appear in the output.

With the FILE1 and FILE2 contents specified in the 1st message in this thread, the output produced by this script is:
Code:
    Date  Time FILE1 FILE2
20130322 05:35  2219   170
20130322 05:40  1809   169
20130322 05:45  1617   172
20130322 05:50  1359   171
20130322 05:55  2233     0
20130322 06:00  1648     0

info

INFO(1) 							   User Commands							   INFO(1)

NAME

       info - read Info documents

SYNOPSIS

       info [OPTION]... [MENU-ITEM...]

DESCRIPTION

       Read documentation in Info format.

OPTIONS

       --apropos=STRING
	      look up STRING in all indices of all manuals.

       -d, --directory=DIR
	      add DIR to INFOPATH.

       --dribble=FILENAME
	      remember user keystrokes in FILENAME.

       -f, --file=FILENAME
	      specify Info file to visit.

       -h, --help
	      display this help and exit.

       --index-search=STRING
	      go to node pointed by index entry STRING.

       -n, --node=NODENAME
	      specify nodes in first visited Info file.

       -o, --output=FILENAME
	      output selected nodes to FILENAME.

       -R, --raw-escapes
	      don't remove ANSI escapes from man pages.

       --restore=FILENAME
	      read initial keystrokes from FILENAME.

       -O, --show-options, --usage
	      go to command-line options node.

       --subnodes
	      recursively output menu items.

       --vi-keys
	      use vi-like and less-like key bindings.

       --version
	      display version information and exit.

       The first non-option argument, if present, is the menu entry to start from; it is searched for in all `dir' files along INFOPATH.  If it is
       not present, info merges all `dir' files and shows the result.  Any remaining arguments are treated as the names of menu items relative	to
       the initial node visited.

EXAMPLES

       info   show top-level dir menu

       info emacs
	      start at emacs node from top-level dir

       info emacs buffers
	      start at buffers node within emacs manual

       info --show-options emacs
	      start at node with emacs' command line options

       info -f ./foo.info
	      show file ./foo.info, not searching dir
