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.

srec_stewie - Stewie's binary file format
DESCRIPTION
If you have a URL for documentation of this format, please let me know.
Any resemblance to the Motorola S-Record is superficial, and extends only to the data records. The header records and termination records
are completely different. None of the other Motorola S-Records record type are available.
The Records
All records start with an ASCII capital S character, value 0x53, followed by a type specifier byte. All records consist of binary bytes.
The Header Record
Each file starts with a fixed four byte header record.
+-----+------+------+------+
|0x53 | 0x30 | 0x30 | 0x33 |
+-----+------+------+------+
The Data Records
Each data record consists of 5 fields. These are the type field, length field, address field, data field, and the checksum. The lines
always start with a capital S character.
+-----+------+---------------+---------+------+----------+
|0x53 | Type | Record Length | Address | Data | Checksum |
+-----+------+---------------+---------+------+----------+
Type The type field is a one byte field that specifies whether the record has a two-byte address field (0x31), a three-byte address
field (0x32) or a four-byte address field (0x33). The address is big-endian.
Record Length
The record length field is a one byte field that specifies the number of bytes in the record following this byte.
Address This is a 2-, 3- or 4-byte address that specifies where the data in the record is to be loaded into memory.
Data The data field contains the executable code, memory-loadable data or descriptive information to be transferred.
Checksum
The checksum is a one byte field that represents the least significant byte of the one's complement of the sum of the values repre-
sented by the bytes making up the record's length, address, and data fields.
The Termination Record
Each file ends with a fixed two byte termination record.
+-----+------+
|0x53 | 0x38 |
+-----+------+
Size Multiplier
In general, binary data will expand in sized by approximately 1.2 times when represented with this format.
EXAMPLE
Here is an hex-dump example file. It contains the data "Hello, World[rq] to be loaded at address 0.
0000: 53 30 30 33 53 31 10 00 00 48 65 6C 6C 6F 2C 20 S003S1...Hello,
0010: 57 6F 72 6C 64 0A 9D 53 38 World..S8
