Returns the time-dependent variable for nonce creation.
Description
A nonce has a lifespan of two ticks. Nonces in their second tick may be updated, e.g. by autosave.
Parameters
$action
string|intoptional- The nonce action.
Default:
-1
Source
function wp_nonce_tick( $action = -1 ) {
/**
* Filters the lifespan of nonces in seconds.
*
* @since 2.5.0
* @since 6.1.0 Added `$action` argument to allow for more targeted filters.
*
* @param int $lifespan Lifespan of nonces in seconds. Default 86,400 seconds, or one day.
* @param string|int $action The nonce action, or -1 if none was provided.

$nonce_life = apply_filters( 'nonce_life', DAY_IN_SECONDS, $action );
return ceil( time() / ( $nonce_life / 2 ) );
}
Hooks
- apply_filters( ‘nonce_life’,
int $lifespan ,string|int $action ) Filters the lifespan of nonces in seconds.
The mathematics of this function actually only guarantees a nonce’s lifespan to be half of the
nonce_life
filtered value but may be up to that value (minus 1 second), depending on the time of day it was generated.See my comment on verifying nonces.
