Hi Everyone,
awk 'BEGIN{print strftime("%c",1272814948)}' | tr -d '\n'

JOIN(1) User Commands JOIN(1)
NAME
join - join lines of two files on a common field
SYNOPSIS
join [OPTION]... FILE1 FILE2
DESCRIPTION
For each pair of input lines with identical join fields, write a line to standard output. The default join field is the first, delimited
by whitespace. When FILE1 or FILE2 (not both) is -, read standard input.
-a FILENUM
print unpairable lines coming from file FILENUM, where FILENUM is 1 or 2, corresponding to FILE1 or FILE2
-e EMPTY
replace missing input fields with EMPTY
-i, --ignore-case
ignore differences in case when comparing fields
-j FIELD
equivalent to `-1 FIELD -2 FIELD'
-o FORMAT
obey FORMAT while constructing output line
-t CHAR
use CHAR as input and output field separator
-v FILENUM
like -a FILENUM, but suppress joined output lines
-1 FIELD
join on this FIELD of file 1
-2 FIELD
join on this FIELD of file 2
--check-order
check that the input is correctly sorted, even if all input lines are pairable
--nocheck-order
do not check that the input is correctly sorted
--header
treat the first line in each file as field headers, print them without trying to pair them
--help display this help and exit
--version
output version information and exit
Unless -t CHAR is given, leading blanks separate fields and are ignored, else fields are separated by CHAR. Any FIELD is a field number
counted from 1. FORMAT is one or more comma or blank separated specifications, each being `FILENUM.FIELD' or `0'. Default FORMAT outputs
the join field, the remaining fields from FILE1, the remaining fields from FILE2, all separated by CHAR.
Important: FILE1 and FILE2 must be sorted on the join fields. E.g., use ` sort -k 1b,1 ' if `join' has no options, or use ` join -t '' '
if `sort' has no options. Note, comparisons honor the rules specified by `LC_COLLATE'. If the input is not sorted and some lines cannot
be joined, a warning message will be given.
