Gosh! I'll have a play with the -k option, I read the man page and didn't understand the k bit at all.
I need column 1 (Epoch time stamp) ignoring and the rest of the line taken into account for comparison. It's free text from interfaces so could be any number of words and characters.

fstrcasecmp
fstrcasecmp(3) Library Functions Manual fstrcasecmp(3)
NAME
fstrcasecmp - fuzzy comparison of two strings ignoring case
SYNOPSIS
#include <fstrcmp.h>
#define FSTRCMP_IDENTICAL
#define FSTRCMP_THRESHOLD
#define FSTRCMP_ERROR
double fstrcasecmp(const char *string1, const char *string2);
DESCRIPTION
The fstrcmp() function compares the two strings, string1 and string2, ignoring case.
RETURN VALUE
The fstrcasecmp function returns a floating point value between 0.0 and FSTRCMP_IDENTICAL. A value of 0.0 means the strings are utterly
un-alike. A value of FSTRCMP_IDENTICAL means the strings are identical. A value of more than FSTRCMP_THRESHOLD (it lies between 0.0 and
FSTRCMP_IDENTICAL) would be considered "similar" by most people.
A value of FSTRCMP_ERROR (always negative) indicates a malloc(3) failure.
