Convert milliseconds to minutes: Getting incorrect result

Question

I have a total ammount of milliseconds (ie 4007587) and I want to display it as hours:minutes:seconds.

my PHP code:

$mil = 4007587
$timestamp = $mil/1000;
echo date("g:i:s", $timestamp);

the result should be 1:06:47 but my result is 8:06:47 what's wrong?

As a general rule when working with dates, ignore the old [date & time PHP functions](http://php.net/manual/en/ref.datetime.php) and use the [`DateTime`](http://php.net/manual/en/book.datetime.php) **classes**. With a couple of exceptions, the old date&time functions do not work with timezones and handling multiple timezones with them is difficult. The classes work with timezones and each `DateTime` object knows the timezone of the date it stores. Working with them is easy and produces more readable code. — axiac, Sep 02 '18 at 08:08

It's because date takes account of your local timezone. Try using gmdate instead:

$mil = 4007587;
$timestamp = $mil/1000;
// local timezone
echo date("g:i:s", $timestamp);
// UTC
echo gmdate("g:i:s", $timestamp);

Output

2:06:47
1:06:47
