Using #config to customize time format and more

On the previous page I showed you SSI's ability to output various server information, such as the size of a file, current date and time etc. This is all great stuff, but a question that quickly follows is "Can I customize the format of the output such as of the date and time?" Sorry, got to learn to just be content! Just kidding. Yes, it's certainly possible, thanks to another SSI command called #config. Take a look at this:

<!--#config timefmt="%m/%d/%y" -->
<!--#echo var="DATE_LOCAL" -->

Output: 09/24/17

Instead of a long string containing both the date and time, I've used #config to pound things into exactly the format I want. Lets see now the various parameters of the #config command at your disposal:

%a abbreviated weekday name Sun
%A full weekday name Sunday
%b abbreviated month name Jan
%B full month name January
%c locale's appropriate date and time Sun Dec 28 04:45:57 2005
%d day of month - 01 to 31 25
%D date as %m/%d/%y 12/25/05
%e day of month - 1 to 31 25
%H hour - 00 to 23 15
%I hour - 01 to 12 03
%j day of year - 001 to 366 361
%m month of year - 01 to 12 12
%M minute - 00 to 59 09
%n insert a newline character  
%p string containing AM or PM PM
%r time as %I:%M:%S %p 06:08:05 PM
%R time as %H:%M 15:09
%S second - 00 to 59 02
%t insert a tab character  
%T time as %H:%M:%S 15:21:07
%U week number of year (Sunday is the first day of the week) - 00 to 53 52
%w day of week - Sunday=0 0
%W week number of year (Monday is the first day of the week) - 00 to 53 51
%x Country-specific date format 12/25/05
%X Country-specific time format 04:50:29
%y year within century - 00 to 99 05
%Y year as CCYY (4 digits) 2005
%Z timezone name PST

Here are a couple more examples:

<!--#config timefmt="%A %d %B, %Y" -->
<!--#echo var="DATE_LOCAL" -->

Output: Sunday 24 September, 2017

<!--#config timefmt="%D %r"-->
This document last modified: <!--#echo var="LAST_MODIFIED" -->

Output: This document last modified: 05/12/15 11:03:52 AM

Formatting file size with #config

So far on this page I've only used the #config command to format time related output. But you can also use this command on file size output:

<!--#config sizefmt="abbrev"-->
<!--#fsize file="current.shtml" -->
<!--#config sizefmt="bytes"-->
<!--#fsize file="current.shtml" -->

The first code tells the server to display the file size in abbreviated form, rounded to the nearest kilobytes. The second example obviously displays the size in bytes instead.
