Convert seconds to compound duration

From Rosetta Code
Task
Convert seconds to compound duration
You are encouraged to solve this task according to the task description, using any language you may know.
Task

Write a function or program which:

  • takes a positive integer representing a duration in seconds as input (e.g., 100), and
  • returns a string which shows the same duration decomposed into weeks, days, hours, minutes, and seconds as detailed below (e.g., "1 min, 40 sec").


Demonstrate that it passes the following three test-cases:

Test Cases

input number output string
7259 2 hr, 59 sec
86400 1 d
6000000 9 wk, 6 d, 10 hr, 40 min

Details

  • The following five units should be used:
    unit suffix used in output conversion
    week wk 1 week = 7 days
    day d 1 day = 24 hours
    hour hr 1 hour = 60 minutes
    minute min 1 minutes = 60 seconds
    second sec
  • However, only include quantities with non-zero values in the output (e.g., return "1 d" and not "0 wk, 1 d, 0 hr, 0 min, 0 sec").
  • Give larger units precedence over smaller ones as much as possible (e.g., return 2 min, 10 sec and not 1 min, 70 sec or 130 sec)
  • Mimic the formatting shown in the test-cases (quantities sorted from largest unit to smallest and separated by comma+space; value and unit of each quantity separated by space).

Fortran[edit]

If the PARAMETER statements were replaced (say with suitable DATA statements) then this could be compiled with Fortran 77, if a find-last-non-blank function were to be supplied and a supplementary scratchpad used so that the numbers could be placed without leading spaces (thus "9" and "10", not " 9") because the I0 format specifier is a F90 facility. Earlier Fortran compilers lacking a CHARACTER variable would present further difficulty.

If the time to describe was not an integer but a floating-point value with fractional parts, then there is a complication. The number of seconds can be less than sixty, but, on output, 60 seconds can appear. If the number of seconds was to be written with one decimal digit (say) and the output format was F4.1 for that, then if the value was 59·95 or more, it will be rounded up for output, in this example to 60·0. Various systems make this mistake, as also with latitude and longitude, and it is a general problem. A fixup pass is necessary before generating the output: maintain an array with the integer values of the various units, then (for one decimal digit usage) check that the seconds part is less than 59·95. If not, set it to zero and augment the minutes count. If this is 60 or more, set it to zero and augment the hours count, and so on. Thus the array.

 
SUBROUTINE PROUST(T) !Remembrance of time passed.

N = S/USIZE(I) !Largest first.
IF (N.GT.0) THEN !Above the waterline?

Perl 6[edit]

The built-in polymod method (which is a generalization of the divmod function known from other languages), is a perfect match for a task like this:

sub compound-duration ($seconds) {
($seconds.polymod(60, 60, 24, 7) Z <sec min hr d wk>)
.grep(*[0]).reverse.join(", ")
}

Demonstration:

for 7259, 86400, 6000000 {
say "{.fmt: '%7d'} sec = {compound-duration $_}";
}
Output:
   7259 sec  =  2 hr, 59 sec
  86400 sec  =  1 d
6000000 sec  =  9 wk, 6 d, 10 hr, 40 min

Phix[edit]

The existing standard function for this gives the results shown

.SYNOPSIS
Gets a time string in the form: # wk, # d, # hr, # min, # sec
.DESCRIPTION
Gets a time string in the form: # wk, # d, # hr, # min, # sec
(Values of 0 are not displayed in the string.)
 
Days, Hours, Minutes or Seconds in any combination may be used
as well as Start and End dates.
 
When used with the -AsObject switch an object containing properties
similar to a System.TimeSpan object is returned.

Rust[edit]

This solution deviates from the prompt a bit in order to make it more general. The benefit of doing it this way is that any values can be filled in for days, hours, minutes and seconds and the `balance` method will do the balancing accordingly. Also, rather than converting the value into a String, it simply implements the `Display` trait.

use std::fmt;
 
 
struct CompoundTime {
w: usize,
d: usize,
h: usize,
m: usize,
s: usize,
}
 
macro_rules! reduce {
($s: ident, $(($from: ident, $to: ident, $factor: expr)),+) => {{
$(
$s.$to += $s.$from / $factor;
$s.$from %= $factor;
)+
}}
}
 
impl CompoundTime {
#[inline]
fn new(w: usize, d: usize, h: usize, m: usize, s: usize) -> Self{
CompoundTime { w: w, d: d, h: h, m: m, s: s, }
}
 
#[inline]
fn balance(&mut self) {
reduce!(self, (s, m, 60), (m, h, 60),
(h, d, 24), (d, w, 7));
}
}
 
impl fmt::Display for CompoundTime {
fn fmt(&self, f: &mut fmt::Formatter) -> fmt::Result {
write!(f, "{}w {}d {}h {}m {}s",
self.w, self.d, self.h, self.m, self.s)
}
}
 
fn main() {
let mut ct = CompoundTime::new(0,3,182,345,2412);
println!("Before: {}", ct);
ct.balance();

Or, if you like to be concise:

fcn toWDHMS(sec){  //-->(wk,d,h,m,s)
T(60,60,24,7).reduce(fcn(n,u,r){ n,u=n.divr(u); r.append(u); n },
sec,r:=List()):r.append(_).reverse();
}

were the ":" op takes the left result and stuffs it into the "_" position.

units:=T(" wk"," d"," hr"," min"," sec");
foreach s in (T(7259,86400,6000000)){
toWDHMS(s).zip(units).pump(List,fcn([(t,u)]){ t and String(t,u) or "" })
.filter().concat(", ").println();
}
Output:
2 hr, 59 sec
1 d
9 wk, 6 d, 10 hr, 40 min
