JavaScript timestamp and PHP Timestamp conversion Considerations _ Basics

Here to note that the time stamp of JS is 13 bits, PHP timestamp is 10 bits, the conversion function is as follows:

Copy Code code as follows:

var nowtime = (new Date). GetTime ();//Current time stamp * *
/* Conversion time, calculated difference * *
function Comptime (begintime,endtime) {
var secondnum = parseint ((endtime-begintime*1000)/1000);//Calculate timestamp difference
if (secondnum>=0&&secondnum<60) {
return secondnum+ ' seconds ago ';
}
else if (secondnum>=60&&secondnum<3600) {
var ntime=parseint (SECONDNUM/60);
return ntime+ ' minutes ago ';
}
else if (secondnum>=3600&&secondnum<3600*24) {
var ntime=parseint (secondnum/3600);
Return ntime+ ' hour ago ';
}
else{
var ntime = parseint (secondnum/86400);
return ntime+ ' days ago ';
}
}
t = comptime ("1324362556", nowtime);//timestamp timestamp for PHP via Ajax
Alert (t);
