I implemented the various methods, ran each in a tight loop 1, times, and compared runtimes and output. My goal for this website is that programmers all around the world know: There was nothing like it in the search results. And timing isn't the easiest problem to solve, especially in a world where GPS has to take into account Einstein's theory of relativity and leap seconds have to be added from time to time to keep UTC Coordinated Universal Time in sync with solar time. NoSQL databases are moving to all-text representations these days so it becomes a bit more important. Leap seconds tend to cause trouble with software. All these timing scripts rely on microtime which relies on gettimebyday 2 This can be inaccurate on servers that run ntp to syncronise the servers time. While doing some experiments on using microtime 's output for an entropy generator I found that its microsecond value was always quantified to the nearest hundreds i. I'll admit I didn't take into account martijn at vanderlee dot com's comments on testing accuracy, but as I figured the looping code etc would be the same, and this was only meant as a relative comparison, it should not be necessary. As i was debugging i needed something to tell me what the current time in ms is.

    The only thing I can think of is try rounding off the decimal portion before converting it to a date. If that doesn't change the result, then the result.
    For accurate timing, since floating-point arithmetic would lose precision, I stored microtime results as-is and calculated time difference with this function: The funniest result i saw was telling me the local time in Millis, Massachusetts.

    1. This is especially good to know if you pass 'true' as the parameter and then calculate the difference between two float values -- the result is already in seconds; it doesn't need to be divided by a million. For accurate timing, since floating-point arithmetic would lose precision, I stored microtime results as-is and calculated time difference with this function:

    2. The Special and General theories of Relativity are taken into account by GPS receivers found in planes, cars and mobile phones and Earth-orbiting satellites to synchronize their time within a nanosecond range. There was nothing like it in the search results.
