elapsedtime

I would like to understand how can I implement elapsed time using jiffies in C. Let's suppose that I have a series of instructions #include <linux/jiffies.h> unsigned long js,je,diff; /***Start Time***/ /*Series of instructions*/ /***End Time***/ Using jiffies, what must I write on my code? Is it right to write so? #include <linux/jiffies.h> unsigned long js,je,diff; unsigned int diffusec; js = jiffies; /***Start Time***/ /*Series of instructions*/ je = jiffies; /***End Time***/ diff = je - js; diffusec = jiffies_to_usecs(diff); Is it right? Using jiffies is better than using getnstimeofday

You can think of this like a really simple stopwatch. I'm trying to hack together a bash script that displays the elapsed time since a specified date and updates the output every second. First, Inside the script you'd specify a UNIX date: Fri Apr 14 14:00:00 EDT 2011 . This would be when the stopwatch starts. Now, when you run the script, you'd see... 06d:10h:37m:01s and a few seconds later you'd see... 06d:10h:37m:05s I'm not trying to have a new line printed for every second that elapses. The script should only have 1 line of output, and update it every second. Obviously you could quit the

I have a SQL Server table that has a "Time" column. The table is a log table the houses status messages and timestamps for each message. The log table is inserted into via a batch file. There is an ID column that groups rows together. Each time the batch file runs it initializes the ID and writes records. What I need to do is get the elapsed time from the first record in an ID set to the last record of the same ID set. I started toying with select Max(Time) - Min(Time) from logTable where id = but couldn't figure out how to format it correctly. I need it in HH:MM:SS. Mike Sherrill 'Cat Recall'

I am developing an android app, which turns the wifi on/off after every 5seconds (5seconds are just for testing) If this information helps: I am using a NavigationDrawer for this app. I am using elapsedRealTime alarm for this. The user selects the time from a dropdown and after the selected time the app turns wifi on/off. For example: When he (the user) selects 30 minutes from the dropdown (spinner), the wifi should be turned on/off after 30minutes. I think that I have everything implemented (like BroadcastReceiver , IntentService ). My Code if it helps. Here is how I call my

On posix it is possible to use timespec to calculate accurate time length (like seconds and milliseconds). Unfortunately I need to migrate to windows with Visual Studio compiler. The VS time.h library doesn't declare timespec so I'm looking for other options. As far as could search is it possible to use clock and time_t although I could't check how precise is counting millisecons with clock counting. What do you do/use for calculating time elapse in a operation (if possible using standards c++ library) ? Grim The function GetTickCount is usually used for that. Also a similiar thread: C++
