/**
 * \class Timer
 * \brief Single-shot timer interface
 *
 * The Timer class models a single-shot timer that is started with start() and
 * emits the \ref timeout signal when it times out.
 *
 * Once started the timer will run until it times out. It can be stopped with
 * stop(), and once it times out or is stopped, can be started again with
 * start().
 *
 * The timer deadline is specified as either a duration in milliseconds or an
 * absolute time point. If the deadline is set to the current time or to the
 * past, the timer will time out immediately when execution returns to the
 * event loop of the timer's thread.
 *
 * Timers run in the thread they belong to, and thus emit the \a ref timeout
 * signal from that thread. To avoid race conditions they must not be started
 * or stopped from a different thread, attempts to do so will be rejected and
 * logged, and may cause undefined behaviour.
