Thanks to Dr Tim Cutts.
I did it in ksh instead, adding 40 if gt than 59 etc, etc.
But Dr Tim suggested.
Fairly easy to do with an in-line perl script:
#!/bin/sh
addtime() {
perl -e 'use integer;
my ($h, $m, $s) = ($ARGV[0] =~ m/\G(\d\d)/g);
if (($s += $ARGV[1]) >= 60) {
$m += ($s/60); $s %= 60;
if ($m >= 60) { $h += ($m/60); $m %= 60; }
$h %= 24;
}
printf "%02d%02d%02d\n", $h,$m,$s;' $1 $2
}
addtime 235859 5
