You can use the following function to convert your timestamp to HH MM SS format   var convertTime   function timestamp  separator        var pad   function input   return input  lt  10    quot 0 quot    input   input        var date   timestamp   new Date timestamp   1000    new Date        return           pad date getHours             pad date getMinutes             pad date getSeconds          join typeof separator      undefined     separator             Without passing a separator  it uses   as the  default  separator   time   convertTime 1061351153      -- gt  OUTPUT   05 45 53  If you want to use   as a separator  just pass it as the second parameter  time   convertTime 920535115           -- gt  OUTPUT   09 11 55   Demo  x000D   x000D  var convertTime   function timestamp  separator        var pad   function input   return input  lt  10    0    input   input        var date   timestamp   new Date timestamp   1000    new Date        return           pad date getHours             pad date getMinutes             pad date getSeconds          join typeof separator      undefined     separator             document body innerHTML     lt pre gt     JSON stringify       920535115   convertTime 920535115            1061351153   convertTime 1061351153            1435651350   convertTime 1435651350   -        1487938926   convertTime 1487938926       1555135551   convertTime 1555135551          null    t        lt  pre gt    x000D   x000D   x000D   See also this Fiddle

Pay attention to the zero problem with some of the answers  For example  the timestamp 1439329773 would be mistakenly converted to 12 08 2015 0 49   I would suggest on using the following to overcome this issue   var timestamp   1439329773     replace your timestamp var date   new Date timestamp   1000   var formattedDate     0    date getDate    slice -2            0     date getMonth     1   slice -2          date getFullYear             0    date getHours    slice -2            0    date getMinutes    slice -2   console log formattedDate     Now results in   12 08 2015 00 49
