&reftitle.description; final public static `void` `Ev::nowUpdate`

Establishes the current time by querying the kernel, updating the time returned by `Ev::now` in the progress. This is a costly operation and is usually done automatically within `Ev::run` .

This method is rarely useful, but when some event callback runs for a very long time without entering the event loop, updating libev 's consideration of the current time is a good idea.
