how to show milliseconds in days:hours:min:seconds
A simple way to calculate the time is to use something like
long seconds = timeInMilliSeconds / 1000;
long minutes = seconds / 60;
long hours = minutes / 60;
long days = hours / 24;
String time = days + ":" + hours % 24 + ":" + minutes % 60 + ":" + seconds % 60;
This will work if you have more than 28 days, but not if you have a negative time.
SimpleDateFormat is your friend! (I just discovered it today, it's awesome.)
SimpleDateFormat formatter = new SimpleDateFormat("dd:HH:mm:ss", Locale.UK);
Date date = new Date(timeInMilliSeconds);
String result = formatter.format(date);
Hi, how about this code ?
example)
0 ms -> 0 ms
846 ms -> 846ms
1,000 ms -> 1s
1,034 ms -> 1s 34ms
60,000 ms -> 1m
94,039 ms -> 1m 34s 39ms
3,600,000 ms -> 1h
61,294,039 ms -> 17h 1m 34s 39ms
86,400,000 ms -> 1d
406,894,039 ms -> 4d 17h 1m 34s 39ms
31,536,000,000 ms -> 1y
50,428,677,591 ms -> 1y 218d 15h 57m 57s 591ms
50,428,677,591 ns -> 50s 428ms 677us 591ns
50,428,677,591 us -> 14h 28s 677ms 591us
50,428,677,591 ms -> 1y 218d 15h 57m 57s 591ms
50,428,677,591 s -> 1599y 30d 5h 59m 51s
50,428,677,591 m -> 95944y 354d 23h 51m
50,428,677,591 h -> 5756698y 129d 15h
50,428,677,591 d -> 138160760y 191d
