I am having a silly issue .. I have read the following which pertain to creating dates as the bottom of a plot chart using flot.js. However my problem persists.:

Understanding Date and Time in JavaScript
And I am still having issues.
Here is my Javascript:

Now the part I am particularly having issues with is :
[1199167200000, 0],[1201845600000, 0],[1204351200000, ...
According to what I have read, a Unix timestamp needs to be multiplied by 1000 since Unix measures in seconds and JS in milliseconds. So in my php that I return, this is how I am getting that timestamp:
$mysql_time = "$year-$month-01"; // Year IE(2017) - Month IE(05) - First day of month (01)
$info_by_month['timestamp'] = strtotime($mysql_time) * 1000;
Basically converting a mysql timestamp to a Unix timestamp, then multiplying by 1000 to get a JS timestamp.
Here is what it returns:
Problem is, they are all showing Jan 01 -- Is my problem in the php, or the JS? How do I return the correct timestamp?
