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
$actionstring|intoptional- The nonce action.
Default:
-1

* @param string|int $action Optional. The nonce action. Default -1.
* @return float Float value rounded up to the next highest integer.
The mathematics of this function actually only guarantees a nonce’s lifespan to be half of the
nonce_lifefiltered 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.
