Convert milliseconds to human readable time lapse

Question

I would like to format some commands execution times in a human readable format, for example:

3 -> 3ms
1100 -> 1s 100ms
62000 -> 1m 2s
etc ..

Taking into account days, hours, minutes, seconds, ...

Is it possible using C#?

Answer 1

You can use TimeSpan class, something like this:

TimeSpan t = TimeSpan.FromMilliseconds(ms);
string answer = string.Format("{0:D2}h:{1:D2}m:{2:D2}s:{3:D3}ms", 
                        t.Hours, 
                        t.Minutes, 
                        t.Seconds, 
                        t.Milliseconds);

It's quite similar as this thread I've just found:

What is the best way to convert seconds into (Hour:Minutes:Seconds:Milliseconds) time?

Answer 2

I know this is old, but I wanted to answer with a great nuget package.

Install-Package Humanizer

https://www.nuget.org/packages/Humanizer

https://github.com/MehdiK/Humanizer

Example from their readme.md

TimeSpan.FromMilliseconds(1299630020).Humanize(4) => "2 weeks, 1 day, 1 hour, 30 seconds"

Answer 3

You could utilize the static TimeSpan.FromMilliseconds method as well as the resulting TimeSpan's Days, Hours, Minutes, Seconds and Milliseconds properties.

But I'm busy right now, so I'll leave the rest to you as an exercise.

Answer 4

What about this?

var ts = TimeSpan.FromMilliseconds(86300000 /*whatever */);
var parts = string
                .Format("{0:D2}d:{1:D2}h:{2:D2}m:{3:D2}s:{4:D3}ms",
                    ts.Days, ts.Hours, ts.Minutes, ts.Seconds, ts.Milliseconds)
                .Split(':')
                .SkipWhile(s => Regex.Match(s, @"00\w").Success) // skip zero-valued components
                .ToArray();
var result = string.Join(" ", parts); // combine the result

Console.WriteLine(result);            // prints '23h 58m 20s 000ms'
