So, no matter what interval I really need, I get a longer interval which is at least 55 ms long. The random number term represents the time left in the 55 ms jiffy when the real-world event actually occurs, and the other term represents the actual time elapsed from the start of the timer to the output of the command to the real-world equipment.
Timer clock plus#
The total elapsed time is 55 ms times a random number in the range [0.1), plus 55 ms times the next highest integer of the quotient of the desired interval divided by 55 ms.
Timer clock windows#
Then, after the interval ends, Windows won't let the command be sent to the real-world equipment until the program's jiffy ends and Windows does the I/O during the mousekeeping period. When the real-world event which is supposed to start the interval occurs, Windows won't let the computer program know about it until the program's jiffy is over and Windows does the I/O during the mousekeeping period. The problem is that Windows takes a time-out every 55 milliseconds to do its mousekeeping, and all I/O must occur during the mouskeeping period. These are necessary for real-time control of equipment. I need to create time intervals in the millisecond range (e.g. If lngLoopCntr > lngMilliSecs then exit Do LngLoopCntr=0 ' although it initializes to 0, but it is a gud practise to initialize variable Private Declare Sub Sleep lib "kernel32" (ByVal dwMilliseconds as long)

You can change the color of the countdown section, and you can also change the background color from white to black (negative). You can choose which music or sound will play and how many times it will repeat. When Free Timer finishes the countdown, your chosen music will start playing, and the timer will stop. Set the interval and click the Start button. You can also change the colors of the timers to distinguish timers from each other. If you need to run several timers simultaneously, you can run the program as many times as you need. No matter what interval you specify, the countdown timer will move the second hand, which will move counterclockwise. As for the countdown, the colored section will steadily decrease in size according to the remaining time.
If the interval is 12 hours or less, the timer counts in hours.If the interval is one hour or less, the timer counts in minutes.If the interval is one minute or less, the timer counts in seconds.The colored section of the clock face will display the time corresponding to the interval you set: You can set the time in seconds, minutes, and hours. The Free Timer program allows you to create countdown timers that display the remaining time as a colored section of a clock face. Free Timer A free, full-featured, and lightweight timer for Windows
