Convert Filetime to time (from variable) PHP

Question

I have a filetime time of '131841804730412861' I do not have a file, I have a filetime coming from an API I am trying to convert it to a "normal" time

Is there a way to decode filetime from a varible in php seeing as Microsoft Filetime has an epoch of Jan 1, 1601 and uses microseconds?

Did you google the function you are trying to use? http://php.net/manual/en/function.date.php — Andreas, Nov 21 '18 at 13:27
It might be a lot of numbers but it does decode to an actual date - https://www.silisoftware.com/tools/date.php?inputdate=131841804730412861&inputformat=filetime — Christopher Taylor, Nov 21 '18 at 13:37
Why on earth do you need a filetime that dates back to 1601? That is several hundred years before any computer was invented. What kind of "file" is this filetime from? — Andreas, Nov 21 '18 at 13:40
I must have misworded it, I was just saying that Microsoft Filettimehas an epoch of Jan 1, 1601 — Christopher Taylor, Nov 21 '18 at 13:41
@Stender That one works perfectly. I had tried some of the solutions from the dupes but they returned the incorrect time. — Christopher Taylor, Nov 21 '18 at 13:46
@ChristopherTaylor No they don't see my link. Maybe it's timezone related? — Andreas, Nov 21 '18 at 13:53
@Stender But not the servers (?). PHP is a serverside language not clientside. — Andreas, Nov 21 '18 at 14:03

date(); takes format as first argument Documentation

Mainly You want to do something like:

$filename = 'somefile.txt';
if (file_exists($filename)) {
    echo "$filename was last modified: " . date ("F d Y H:i:s.", filemtime($filename));
}

btw. Number You gave in question is too large.

filemtime — Gets file modification time and it returns the time the file was last modified, or FALSE on failure. The time is returned as a Unix timestamp, which is suitable for the date() function.

So, this should work for you but I've a doubt that your given string '131841804730412861' is a valid unix timestamp because too high in lenght.

date ("F d Y H:i:s.", filemtime($filename));
