I am reading the chapter single.dvi of OSTEP. In the homework part, it says: One thing you’ll have to take into account is the precision and accuracy of your timer. A typical timer that you can us...

Could someone please help me to use gettimeofday() function with Visual Studio C++ 2008 on Windows XP? here is a code that I found somewhere on the net: #include < time.h > #include <wind...

In Java System.nanoTime()'s monotonic implementation on Linux relies on the fact that CLOCK_MONOTONIC is available on the OS. If it's not available, it falls back to gettimeofday which can result i...

I am working on some C code that is implementing a triple nested for loop to calculate matrix-matrix multiplication while parallelizing it using OpenMP. I am trying to accurately measure the amount...

I have following C code: uint64_t combine(uint32_t const sec, uint32_t const usec){ return (uint64_t) sec << 32 | usec; }; uint64_t now3(){ struct timeval tv; gettimeofday(&tv, NULL...

On the two systems I've tested (a 32-bit Ubuntu 12.04 server and a 64-bit Ubuntu 13.10 VM), the seconds since the epoch given by time() may differ from gettimeofday()'s. Specifically, though I cal...

I have an experimental library whose performance I'm trying to measure. To do this, I've written the following: struct timeval begin; gettimeofday(&begin, NULL); { // Experiment! } struct tim...

The code in Swift ... var time:timeval? gettimeofday(UnsafePointer<timeval>, UnsafePointer<()>) // this is the method expansion before filling in any data ... The code in Objective C...

In trying to build a very latency sensitive application, that needs to send 100s of messages a seconds, each message having the time field, we wanted to consider optimizing gettimeofday. Out first...

I've a program to calculate the latency of an object in a pub-sub model. I've used the following function for timestamp: uint64_t GetTimeStamp() { struct timeval tv; gettimeofday(&tv,NULL); ...

The time command returns the time elapsed in execution of a command. If I put a "gettimeofday()" at the start of the command call (using system() ), and one at the end of the call, and take a diff...

I'm writing a portable Socket class that supports timeouts for both sending and receiving... To implement these timeouts I'm using select().... But, I sometimes need to know how long I was bl...

I've tried Google, php.net and the php mailinglist's archives, but I can't find what I'm looking for. Maybe it's obvious, or maybe nobody wonders about this... For years, I've used microtime() to ...

I do not really wish to profile because I was wanting to do many different small benchmarks on different simple functions. For the life of me I cannot find a way to record the amount of millisecond...

While testing Pythons time.clock() function on FreeBSD I've noticed it always returns the same value, around 0.156 The time.time() function works properly but I need a something with a slightly hi...
