Gets the time to be used when checking this source. The advantage of
calling this function over calling g_get_monotonic_time() directly is
that when checking multiple sources, GLib can cache a single value
instead of having to repeatedly get the system monotonic time.
The time here is the system monotonic time, if available, or some
other reasonable alternative otherwise. See g_get_monotonic_time().
