    • wallClockTime

      public long wallClockTime()
      Specified by:
      wallClockTime in interface TimeService
      Returns:
      the current clock time in milliseconds. Note that it depends of the system time.

    • time

      public long time()
      Specified by:
      time in interface TimeService
      Returns:
      the current cpu time in nanoseconds. Note that some platforms do not provide nanosecond precision.

    • instant

      public Instant instant()
      Specified by:
      instant in interface TimeService
      Returns:
      the current Instant. Similarly to TimeService.time(), note that some platforms do not provide nanosecond precision.

    • timeDuration

      public long timeDuration(long startTimeNanos, TimeUnit outputTimeUnit)
      Description copied from interface: TimeService
      It is equivalent to timeDuration(startTime, time(), outputTimeUnit).
      Specified by:
      timeDuration in interface TimeService
      Parameters:
      startTimeNanos - start cpu time in nanoseconds, usually returned by TimeService.time().
      outputTimeUnit - the TimeUnit of the returned value.
      Returns:
      the duration between the current cpu time and startTime. It returns zero if startTime is less than zero or if startTime is greater than the current cpu time.

    • timeDuration

      public long timeDuration(long startTimeNanos, long endTimeNanos, TimeUnit outputTimeUnit)
      Specified by:
      timeDuration in interface TimeService
      Parameters:
      startTimeNanos - start cpu time in nanoseconds, usually returned by TimeService.time().
      endTimeNanos - end cpu time in nanoseconds, usually returned by TimeService.time().
      outputTimeUnit - the TimeUnit of the returned value.
      Returns:
      the duration between the endTime and startTime. It returns zero if startTime or endTime are less than zero or if startTime is greater than the endTime.

    • isTimeExpired

      public boolean isTimeExpired(long endTimeNanos)
      Specified by:
      isTimeExpired in interface TimeService
      Parameters:
      endTimeNanos - a cpu time in nanoseconds, usually returned by TimeService.time()
      Returns:
      true if the endTime is less or equals than the current cpu time.

    • remainingTime

      public long remainingTime(long endTimeNanos, TimeUnit outputTimeUnit)
      Specified by:
      remainingTime in interface TimeService
      Parameters:
      endTimeNanos - the end cpu time in nanoseconds.
      outputTimeUnit - the TimeUnit of the returned value.
      Returns:
      the remaining cpu time until the endTime is reached.

    • expectedEndTime

      public long expectedEndTime(long duration, TimeUnit inputTimeUnit)
      Specified by:
      expectedEndTime in interface TimeService
      Parameters:
      duration - the duration.
      inputTimeUnit - the TimeUnit of the duration.
      Returns:
      the expected end time in nano seconds. If duration is less or equals to zero, the current cpu time is returned (TimeService.time()).
