Were it a fixed width file, things would be much simpler. The following does work on your sample but will fail if positions of spaces and fields shift:
This will work on many systems. Unfortunately the standards are silent as to which line with identical keys will be printed by sort -u so there is no guarantee that it will always print the 1st line in each set of lines with identical strings in the 1st three characters of the line.
The following should work portably (as long as the 8 digit date string starts in column 13 or 14 and is preceded by a space if it starts in column 14):
But, of course, if you want to try this on a Solaris/SunOS system, you'd have to change awk to /usr/xpg4/bin/awk, /usr/xpg6/bin/awk, or nawk.

join
JOIN(1) General Commands Manual JOIN(1)NAME
join - relational database operator
SYNOPSIS
join [ options ] file1 file2
DESCRIPTION
Join forms, on the standard output, a join of the two relations specified by the lines of file1 and file2. If file1 is `-', the standard
input is used.
File1 and file2 must be sorted in increasing ASCII collating sequence on the fields on which they are to be joined, normally the first in
each line.
There is one line in the output for each pair of lines in file1 and file2 that have identical join fields. The output line normally con-
sists of the common field, then the rest of the line from file1, then the rest of the line from file2.
Fields are normally separated by blank, tab or newline. In this case, multiple separators count as one, and leading separators are dis-
carded.
These options are recognized:
-an In addition to the normal output, produce a line for each unpairable line in file n, where n is 1 or 2.
-e s Replace empty output fields by string s.
-jn m Join on the mth field of file n. If n is missing, use the mth field in each file.
-o list
Each output line comprises the fields specifed in list, each element of which has the form n.m, where n is a file number and m is a
field number.
-tc Use character c as a separator (tab character). Every appearance of c in a line is significant.
SEE ALSO sort(1), comm(1), awk(1)BUGS
With default field separation, the collating sequence is that of sort -b; with -t, the sequence is that of a plain sort.
The conventions of join, sort, comm, uniq, look and awk(1) are wildly incongruous.
