What is microtime() in PHP?

The microtime() function is an inbuilt function in PHP which is used to return the current Unix timestamp with microseconds. Return Value: It returns the string microsec sec by default, where sec is the number of seconds since the Unix Epoch (0:00:00 January 1, 1970, GMT), and microsec is the microseconds part.

What is micro time?

Definition of microtime : a very short interval of time (as 0.01 millionth of a second) microtime photography.

What is Microtime true?

microtime(true) on the other hand returns the current time in seconds since the Unix epoch accurate to the nearest microsecond (see PHP reference). It’s actually very easy to test if you run the above code in a loop and display the milliseconds.

What is the difference between milliseconds and microseconds?

A microsecond is an SI unit of time equal to one millionth (0.000001 or 10−6 or 1⁄1,000,000) of a second. A microsecond is equal to 1000 nanoseconds or 1⁄1,000 of a millisecond.

How do I read a Unix timestamp?

To find the unix current timestamp use the %s option in the date command. The %s option calculates unix timestamp by finding the number of seconds between the current date and unix epoch. You will get a different output if you run the above date command.

How does PHP calculate elapsed time?

php // pass in the number of seconds elapsed to get hours:minutes:seconds returned function secondsToTime($s) { $h = floor($s / 3600); $s -= $h * 3600; $m = floor($s / 60); $s -= $m * 60; return $h. ‘:’. sprintf(‘%02d’, $m). ‘:’.

Is msec millisecond or microsecond?

A millisecond (ms or msec) is one thousandth of a second and is commonly used in measuring the time to read to or write from a hard disk or a CD-ROM player or to measure packet travel time on the Internet. For comparison, a microsecond (us or Greek letter mu plus s) is one millionth (10-6) of a second.

What is MU second?

A microsecond is an SI unit of time equal to one millionth (0.000001 or 10−6 or 1⁄1,000,000) of a second. Its symbol is μs, sometimes simplified to us when Unicode is not available. A microsecond is equal to 1000 nanoseconds or 1⁄1,000 of a millisecond.

What is faster milliseconds or microseconds?

A microsecond is equal to 1000 nanoseconds or 1⁄1,000 of a millisecond.

How long is a millisecond?

A millisecond (from milli- and second; symbol: ms) is a thousandth (0.001 or 10−3 or 1/1000) of a second.

How to get millisecond precision on a timestamp?

As other have stated, you can use microtime() to get millisecond precision on timestamps. From your comments, you seem to want it as a high-precision UNIX Timestamp. Something like DateTime.Now.Ticks in the .NET world.

How many milliseconds does 1000*time() give you?

Sep 7 ’10 at 8:11 @COMer: 1000*time()won’t give you milliseconds. microtime(true)returns a floatwhich has 14 digits of precision. The seconds part already took 10, so that left 4 digits for the microseconds part.
