This filter is applied to dates to present them in various formats.
-  |affdate displays the date in text form, e.g. "13 January 2001".
It can be passed a date formatting parameter that corresponds either to a SPIP format ("'saison'", etc.) or to a PHP date command format ("'Y-m-d'").
For example:
[(#DATE|affdate{'Y-m'})] 
... will display the numerical year and month of the date, separated by a hyphen,
The syntax [(#DATE|affdate{'saison'})] is completely identical in operation to : [(#DATE|saison)].
- There are also variants of affdate which offer some common short-cuts: |affdate_court, |affdate_jourcourt and |affdate_mois_annee.
