 Returns the time the last event loop iteration has been started. This
 is the time that (relative) timers are based on, and refering to it is
 usually faster then calling EV::time.

 or EV::METHOD_EPOLL).

 The $flags argument can be one of the following:

 =head2 WATCHER
 Calls the callback after C<$after> seconds. If C<$repeat> is non-zero,
 the timer will be restarted (with the $repeat value as $after) after the
 callback returns.

+The timer is based on a monotonic clock, that is, if somebody is sitting
 in front of the machine while the timer is running and changes the system
 clock, the timer will nevertheless run (roughly) the same time.
 The C<timer_ns> variant doesn't start (activate) the newly created watcher.
 =item $w->again
 Similar to the C<start> method, but has special semantics for repeating timers:
+If the timer is active and non-repeating, it will be stopped.
 If the timer is active and repeating, reset the timeout to occur
 C<$repeat> seconds after now.
-If the timer is active and non-repeating, it will be stopped.
-If the timer is in active and repeating, start it.
+If the timer is inactive and repeating, start it using the repeat value.
 Otherwise do nothing.
 This behaviour is useful when you have a timeout for some IO
 operation. You create a timer object with the same value for C<$after> and
 possible time where C<$time = $at (mod $interval)>, regardless of any time
 jumps.
