Simple one-liner

$ secs=236521
$ printf '%dh:%dm:%ds\n' $(($secs/3600)) $(($secs%3600/60)) $(($secs%60))
65h:42m:1s

With leading zeroes

$ secs=236521
$ printf '%02dh:%02dm:%02ds\n' $(($secs/3600)) $(($secs%3600/60)) $(($secs%60))
65h:42m:01s

With days

$ secs=236521
$ printf '%dd:%dh:%dm:%ds\n' $(($secs/86400)) $(($secs%86400/3600)) $(($secs%3600/60)) \
  $(($secs%60))
2d:17h:42m:1s

With nanoseconds

$ secs=21218.6474912
$ printf '%02dh:%02dm:%02fs\n' $(echo -e "$secs/3600\n$secs%3600/60\n$secs%60"| bc | xargs echo)
05h:53m:38.647491s
