    Default How can i store time in a variable for comparsion?

    I'm not sure how to store time in a variable without it having the value of current run time
    I've never done this before.

    scenario
    ( don't look to much into the scenario as it's the theory of storing time I'm interested in learning. )
    (Id have the same question about timers too)

    I have a thread the thread sleeps for a time period called thread_sleep_time
    I created one more variable called thread_total_sleep_time that is thread_total_sleep_time += thread_sleep_time, every time the thread is sleeps.

    but how can I capture store a time in a variable called previous_time ? must I use keyword final so it never updates ?
    for comparing against the current time.

    Thank you

    What kind of value is the "time" you want to work with?
    The one often used on computers is the number of millisecs since some point in time.

    how can I capture store a time in a variable called previous_time
    Use an assignment statement to give the variable a value.

    so it never updates
    Only executing the assignment statement once will keep it from being updated.
    If you don't understand my answer, don't ignore it, ask a question.

    I'm not sure I'm bit confused to be honest.
    I need to do this sort of thing

    if(thread_current_total_sleep_time == thread_previous_total_sleep_time + 2000000)
    {
    update_previous_and _current() // somthing like this.
    }

    or something similar i will know how much time has passed since a last interval update

    I'm confused at what you're trying to do. Is it more than just the basic, checking system time? i.e.,

          long initialTime = System.currentTimeMillis();
          while (somethingIsTrue) {
     
              // .... do something
     
          } 
     
          long finalTime = System.currentTimeMillis();
     
          long mSecDiff = finalTime - initialTime;
