Class SystemTime


  • public class SystemTime
    extends java.lang.Object
    Utility class to retrieve current system time, and catch clock backward time changes.
    • Constructor Detail

      • SystemTime

        public SystemTime()
    • Method Detail

      • useRawProvider

        public static void useRawProvider()
      • getCurrentTime

        public static long getCurrentTime()
        Note that this can this time can jump into the future or past due to clock adjustments use getMonotonousTime() if you need steady increases
        Returns:
        current system time in millisecond since epoch
      • getMonotonousTime

        public static long getMonotonousTime()
        Time that is guaranteed to grow monotonously and also ignores larger jumps into the future which might be caused by adjusting the system clock

        Do not mix times retrieved by this method with normal time!
        Returns:
        the amount of real time passed since the program start in milliseconds
      • getSteppedMonotonousTime

        public static long getSteppedMonotonousTime()
        Like getMonotonousTime but only updated at TIME_GRANULARITY_MILLIS intervals (not interpolated) As such it is likely to be cheaper to obtain
        Returns:
      • getOffsetTime

        public static long getOffsetTime​(long offsetMS)
      • getHighPrecisionCounter

        public static long getHighPrecisionCounter()
      • main

        public static void main​(java.lang.String[] args)
