php strtotime一周前错了吗？

Question

I need to get the milliseconds of exactly on week ago.

I tried this:

$this->weekDate = strtotime("-1 week");
echo($this->weekDate);

it returns:

1422536434

which according to this conversion tool: http://www.fileformat.info/tip/java/date2millis.htm is

Samstag, 17. Januar 1970 11:08 Uhr GMT

Anybody an idea what is wrong?

The above code is printing the time in seconds Use the code below

$this->weekDate = strtotime("-1 week");
echo($this->weekDate * 1000);

The output of the above code will be

1,422,536,434,000

Hope this helps you
