         When this is the case, you can call this method, which will update

+        A typical example would be a script in a web server (e.g.
+        "mod_perl") - when mod_perl executes the script, then the event loop
+        will have the wrong idea about the "current time" (being potentially

+        web server process wakes up again (e.g. at the start of your script,
+        or in a handler).

         Note that updating the time *might* cause some events to be handled.
