Date and Time Formats with SSI.

author: jim.cerny@unh.edu

This is an experiment with date formats.

For all these examples, view the HTML source before parsing to see the SSI directives used. In each of these examples the LAST_MODIFIED date for this file is inserted by use of the SSI "echo" directive. To control the date format make use of the SSI "config" directive to set the "timefmt" attribute, using one or more date codes, as needed. These codes are those used by the Unix "strftime" routine and are not intuitively obvious. See the strftime man page, as taken from RedHat Linux 6.0, for the list of available format codes. Note that case is significant on these codes.

• The default date format used by SSI contains lots of detail.
