Libev represents time as a single floating point number, representing the
(fractional) number of seconds since the (POSIX) epoch (somewhere near
called C<ev_tstamp>, which is what you should use too. It usually aliases
to the double type in C.

If you use threads, a common model is to run the default event loop

create, you also create another event loop. Libev itself does no locking
whatsoever, so if you mix calls to the same event loop in different
threads, make sure you lock (this is usually a bad idea, though, even if

Prepare and check watchers are usually (but not always) used in tandem:
