# date_format

This formats a date and time into the given `strftime()` format. Dates can be passed to Smarty as unix timestamps, mysql timestamps or any string made up of month day year, parsable by php's `strtotime()`. Designers can then use `date_format` to have complete control of the formatting of the date. If the date passed to `date_format` is empty and a second parameter is passed, that will be used as the date to format.

Parameter Position | Type | Required | Default | Description
--- | --- | --- | --- | ---
1 | string | No | %b %e, %Y | This is the format for the outputted date.
2 | string | No | n/a | This is the default date if the input is empty.

> Note: Since Smarty-2.6.10 numeric values passed to `date_format` are always (except for mysql timestamps, see below) interpreted as a unix timestamp.

> Before Smarty-2.6.10 numeric strings that where also parsable by `strtotime()` in php (like `YYYYMMDD`) where sometimes (depending on the underlying implementation of `strtotime()`) interpreted as date strings and NOT as timestamps.

> The only exception are mysql timestamps: They are also numeric only and 14 characters long (`YYYYMMDDHHMMSS`), mysql timestamps have precedence over unix timestamps.

> Programmers note: `date_format` is essentially a wrapper to PHP's `strftime()` function. You may have more or less conversion specifiers available depending on your system's `strftime()` function where PHP was compiled. Check your system's manpage for a full list of valid specifiers.

Example 5-8. date_format
`<?php $config['date'] = '%I:%M %p'; $config['time'] = '%H:%M:%S'; $smarty->assign('config', $config); $smarty->assign('yesterday', strtotime('-1 day')); ?>`
This template uses `$smarty.now` to get the current time:
    {$smarty.now|date_format}
    {$smarty.now|date_format:"%D"}
    {$smarty.now|date_format:$config.date}
    {$yesterday|date_format}
    {$yesterday|date_format:"%A, %B %e, %Y"}
    {$yesterday|date_format:$config.time}
This above will output:
    Jan 1, 2022
    01/01/22
    02:33 pm
    Dec 31, 2021
    Monday, December 1, 2021
    14:33:00
