Getting date format m-d-Y H i s u from milliseconds

Question

I am trying to get a formatted date  including the microseconds from a UNIX timestamp specified in milliseconds  The only problem is I keep getting 000000  e g   milliseconds   1375010774123   d   date  quot m-d-Y H i s u quot    milliseconds 1000   print  d    07-28-2013 11 26 14 000000

You can readily do this this with the input format U.u.

$now = DateTime::createFromFormat('U.u', microtime(true));
echo $now->format("m-d-Y H:i:s.u");

This produces the following output:

04-13-2015 05:56:22.082300

From the PHP manual page for date formats:

U = Seconds since the Unix Epoch
u = Microseconds

http://php.net/manual/en/function.date.php

Thanks goes to giggsey for pointing out a flaw in my original answer, adding number_format() to the line should fix the case of the exact second. Too bad it doesn't feel quite as elegant any more...

$now = DateTime::createFromFormat('U.u', number_format(microtime(true), 6, '.', ''));

http://php.net/manual/en/function.number-format.php

A note on time zones in response to DaVe.

Normally the createFromFormat() method will use the local time zone if one is not specified.

http://php.net/manual/en/datetime.createfromformat.php

However, the technique described here is initialising the DateTime object using microtime() which returns the number of seconds elapsed since the Unix Epoch (01 Jan 1970 00:00:00 GMT).

http://php.net/manual/en/function.microtime.php

This means that the DateTime object is implicitly initialised to UTC, which is fine for server internal tasks that just want to track elapsed time.

If you need to display the time for a particular time zone then you need to set it accordingly. However, this should be done as a separate step after the initialisation (not using the third parameter of createFromFormat()) because of the reasons discussed above.

The setTimeZone() method can be used to accomplish this requirement.

http://php.net/manual/en/datetime.settimezone.php

As an example:

$now = DateTime::createFromFormat('U.u', number_format(microtime(true), 6, '.', ''));
echo $now->format("m-d-Y H:i:s.u") . '<br>';

$local = $now->setTimeZone(new DateTimeZone('Australia/Canberra'));
echo $local->format("m-d-Y H:i:s.u") . '<br>';

Produces the following output:

10-29-2015 00:40:09.433818
10-29-2015 11:40:09.433818

Note that if you want to input into mysql, the time format needs to be:

format("Y-m-d H:i:s.u")

As of PHP 7 1 you can simply do this    date   new DateTime   NOW     echo  date- gt format   m-d-Y H i s u       It will display as   04-11-2018 10 54 01 321688

Here s a slightly shorter approach   Rather than work to create a high-precision numeric date time  I convert the microsecond value to a string  remove the 0  and add it to the end of the date time string   I can easily trim the number of decimals by adjusting the string length parameter  here I use 4 to get milliseconds  but you could use 7 to get microseconds    t   explode     microtime     echo date  m-d-y H i s   t 1   substr  string  t 0  1 4     For a microtime   value of 0 98236000 1407400573  this returns 08-07-14 01 08 13 982

For PHP 8 0  The bug has been recently fixed and now you can use UNIX timestamps with a fractional part   milliseconds   1375010774123    d   new DateTime        milliseconds 1000    print  d- gt format  quot m-d-Y H i s u quot     Output   07-28-2013 11 26 14 123000  For PHP  lt  8 0 You need to specify the format of your UNIX timestamp before you can use it in the DateTime object  As noted in other answers  you can simply work around this bug by using createFromFormat   and number format    milliseconds   1375010774123    d   DateTime  createFromFormat  U v   number format  milliseconds 1000  3             print  d- gt format  quot m-d-Y H i s u quot     Output   07-28-2013 11 26 14 123000  For PHP  lt  7 3 If you are still using PHP older than 7 3 you can replace U v with U u  It will not make any difference  but the millisecond format identifier is present only since PHP 7 3   milliseconds   1375010774123                                     V - Use microseconds instead of milliseconds  d   DateTime  createFromFormat  U u   number format  milliseconds 1000  3             print  d- gt format  quot m-d-Y H i s u quot     Output   07-28-2013 11 26 14 123000

If you want to format a date like JavaScript s  new Date    toISOString   for some reason  this is how you can do it in PHP    now   microtime true   gmdate  Y-m-d TH i s    now  sprintf    03dZ  round   now-floor  now   1000      Sample output   2016-04-27T18 25 56 696Z     Just to prove that subtracting off the whole number doesn t reduce the accuracy of the decimal portion    gt  gt  gt  number format 123 01234567890123456789 25    gt   123 0123456789012408307826263   gt  gt  gt  number format 123 01234567890123456789-123 25    gt   0 0123456789012408307826263    PHP did round the decimal places  but it rounded them the same way in both cases
