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.

This is detailed below (e.g., "2 hr, 59 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 minute = 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).

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.

Implementation:

fmtsecs=: verb define
  seq=. 0 7 24 60 60 #: y
  }: ;:inv ,(0 ~: seq) # (8!:0 seq) ,. <;.2'wk,d,hr,min,sec,'
)

The first line uses integer division with remainder to break the value in seconds into its components (weeks, days, hours, minutes, seconds).

The second line gives each value a label and a trailing comma, drops the parts which have a zero, combines the rest and then removes the trailing comma from the end of the resulting line.

Task examples:

   fmtsecs 7259
2 hr, 59 sec
   fmtsecs 86400
1 d
   fmtsecs 6000000

Using the “times” module

It is also possible to use the Duration type in the “times” module and the procedure “toParts” which decomposes a duration in units of time (nanoseconds, microseconds, milliseconds, seconds, minutes, hours, days and weeks).

import times
from algorithm import reversed
from strutils import addSep

const Units = [" wk", " d", " hr", " min", " sec"]

  ## Convert a duration in seconds to a friendly string.
  ## Similar to `$` but with other conventions.

  let parts = reversed(duration.toParts[Seconds..Weeks])

  for idx, part in parts:

sub compound_duration {

    my @durations = reverse polymod($seconds, 60, 60, 24, 7);
    my @timespans = <wk d hr min sec>;
    while (my $d = shift @durations, my $t = shift @timespans) {
        push @terms, "$d $t" if $d
    }
    join ', ', @terms
}

for (<7259 86400 6000000 3380521>) {
    printf "%7d sec  =  %s\n", $_, compound_duration($_)

Output:

   7259 sec  =  2 hr, 59 sec
  86400 sec  =  1 d
6000000 sec  =  9 wk, 6 d, 10 hr, 40 min

Phix

There is a standard function for this, for more details see builtins/pelapsed.e (which will be kept up to date, unlike having a copy here)

with javascript_semantics
?elapsed(7259)
?elapsed(86400)
?elapsed(6000000)

Output:

"2 hours and 59s"
"1 day"
"9 weeks, 6 days, 10 hours, 40 minutes"

You may also be interested in the timedelta() function, which converts durations to seconds, eg:

with javascript_semantics
include timedate.e
?elapsed(6000000-timedelta(days:=6,hours:=10))

Output:

"9 weeks, 40 minutes"

Raku

(formerly Perl 6)

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

Rust

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);
