# {html_select_time}
|
|
|
|
`{html_select_time}` is a [custom function](index.md)
|
|
that creates time dropdowns for you. It can display any or all of: hour,
|
|
minute, second and meridian.
|
|
|
|
The `time` attribute can have different formats. It can be a unique
|
|
timestamp, a string of the format `YYYYMMDDHHMMSS` or a string that is
|
|
parseable by PHP's [`strtotime()`](https://www.php.net/strtotime).
