They are no function I'm aware, but it is easy to implement:

Code:

function hms(s)

{

  h=int(s/3600);

  s=s-(h*3600);

  m=int(s/60);

  s=s-(m*60);

  printf("%d:%02d:%02d\n", h, m, s);

}

There are no time builtin functions in the standard awk / nawk, but gnu awk does have these extensions:
mktime
strftime
systime

They are documented in the gawk manual page

you could make a script :

Code:

#!/bin/bash



seconds=0



echo -n "Enter number of seconds : "

read seconds



hours=$((seconds / 3600))

seconds=$((seconds % 3600))

minutes=$((seconds / 60))

seconds=$((seconds % 60))



echo "$hours hour(s) $minutes minute(s) $seconds second(s)"

save this to a file and name it seconds.sh

then type :
su
<your root password>
chmod a+x seconds.sh

then to execute it type : ./seconds.sh

P.S: i didnt write this script , i found it before and sorry i cant remember where i got it from

heema,
- the OP asked for awk and you sent a shell script.
- there's absolutely no need to become root to chmod a file to be executable.

try this:

Code:

print strftime("%H:%M:%S", 3620);

Ugly, but works...

You seem correct, but AWK seems to make some strange assumptions.
apparently, 433 seconds translates into 01:07:11:

Code:

echo |awk '{print strftime("%H:%M:%S", 433)}'

01:07:13

Everything looks OK once you drop off the hour, but that means losing any minutes over 60

Code:

echo |awk '{print strftime("%M:%S", 433)}'

07:13

I have regressed into division and casing to get the type I was looking for:

Code:

echo |awk '{print int(433/60)":"int(433%60)}'

7:13

This will scale over 60 minutes:

Code:

echo |awk '{print int(4000/60)":"int(4000%60)}'

66:40

It looks like strftime() is sensitive to timezones. I played around with setting $TZ, and it affected the result of strftime(). I would post an example, but I'm not conversant enough in matters of timezones to give an example I know isn't nonsensical.

I like this best from an earlier post in the same thread. It's simple, understandable and generic.

Quote:

Code:
function hms(s)
{
h=int(s/3600);
s=s-(h*3600);
m=int(s/60);
s=s-(m*60);
printf("%d:%02d:%02d\n", h, m, s);
}

You're entirely correct.
I forgot this part when reading up on strftome():

strftime([format [, timestamp [, utc-flag]]])
This function returns a string. It is similar to the function of the same name in ISO C. The time specified by timestamp is used to produce a string, based on the contents of the format string. If utc-flag is present and is either non-zero or non-null, the value is formatted as UTC.

It works like a charm:

Code:

 echo |awk '{print strftime("%H:%M:%S", 433,1)}'

00:07:13

Thanks for the tip!

echo "3661" | awk '{print int($0/3600),int($0%3600/60),$0%3600%60}'

All times are GMT -5. The time now is 12:11 AM.
