Usage

---

var result = convertMilliseconds(3661000, "hh:m:s");

result.hours;    // --> 1 hour 
result.minuets;  // --> 1 min
result.seconds;  // --> 1 sec
result.clock;    // --> "01:1:1"

More Examples

convertMilliseconds(milliseconds, pattern);

convertMilliseconds(3661000);
convertMilliseconds(3661000, "hh:mm:ss");
convertMilliseconds(3661000, "mm:hh:ss");
convertMilliseconds(3661000, "ss:mm:hh");
convertMilliseconds(3661000, "mm:ss");
convertMilliseconds(3661000, "ss");
convertMilliseconds(3661000, "h:m:s");
convertMilliseconds(3661000, "m:s");
convertMilliseconds(3661000, "s");

// convertMilliseconds returns object...

var obj = convertMilliseconds(3661000);
obj.hours === 1
obj.minuets === 1
obj.seconds === 1
obj.clock === "01:01:01"
