The default representation of dates is a compact string such as `20211002153802059`. For example, the `created` and `modified` fields are stored like this.
|
|
|
|
The display format for this string can be controlled with a template. For example, transcluding the `modified` field automatically applies a template to display the date as `Sat Oct 02 2021 17:40:50 GMT+0200 (Central European Summer Time)`. A few widgets and filter operators allow you to manually specify a template, for example the ViewWidget:
|
|
|
|
`<$view field=modified format=date template=“DDth mmm YYYY 0hh:0mm:0ss” />`
|
|
|
|
The date string is processed with the following substitutions:
|
|
|
|

|`ddddd` |<<.from-version "5.2.0">> Day of year (1 to 365, or 366 for leap years) |
