javascript - date time issue moment -

sometimes timestamp more 10 digits. using moment js function is:

moment.unix(timestamp).format('yyyy-mm-dd hh:mm') 

when 10 digits long giving me perfect answer. when more 10 digits. don't know why giving wrong year.

sample: correct: 1433167001 gives me 2015-06-01 13:56 incorrect: 1433287744646 gives me date: 47389-01-29 12:37

i tried /1000 not working

code

 - var timestamp =''                                 - if (typeof(res[j]['timestamp']) !== 'undefined'){                                     - timestamp = math.floor(res[j]['timestamp']);                                     - if (timestamp.length > 10) {                                         - timestamp = math.floor(timestamp/1000)                                     - }                                 -}                                  tr                                     td #{index++}                                     td #{results[i]['userinfo']['username']}                                     td #{typename}                                     td #{value}                                     td #{moment.unix(timestamp).format('yyyy-mm-dd hh:mm')} 

the above code in jade.

traditionally, term "unix timestamp" refers number of seconds have elapsed since midnight, january 1st 1970 utc (not counting leap seconds).

var m = moment.unix(numberofseconds); 

however, javascript , many other platforms define timestamps in terms of milliseconds instead of seconds.

var m = moment(numberofmilliseconds); 

it important understand source of data know whether timestamps in terms of seconds or milliseconds. if guess based upon number of digits, excluding range of possible values.
