wp_nonce_tick()WP 2.5.0

Returns the time-dependent variable for nonce creation.

A nonce has a lifespan of two ticks. Nonces in their second tick may be updated, e.g. by autosave.

Pluggable function — this function can be replaced from a plugin. It means that this function is defined (works) only after all plugins are loaded (included), but before this moment this function has not defined. Therefore, you cannot call this and all functions depended on this function directly from a plugin code. They need to be called on plugins_loaded hook or later, for example on init hook.

Function replacement (override) — in must-use or regular plugin you can create a function with the same name, then it will replace this function.

Hooks from the function

Return

float. Float value rounded up to the next highest integer.

Usage

$action(string|int)
