HP-UX shell or OE access to epoch secs

>Sandman!:  printf("%ld\n", time(ptloc));

There is no need to pass a parm to time(2). This also makes the kernel sweat because it has to validate it. Just use time(NULL).

Hello Guys,

many thanks for all the efforts you took further elaborating on my somewhat idle query.

Not actually Laurie, but wanted to share a similar solution to Clays but hopefully easier for them young folk to support once I am gone (first version used bc(1) just because I wanted to try :-):

function secsFromEpoch {

# Good until 2100

typeset -i year=0
typeset -i jDay=0
typeset -i hour=0
typeset -i min=0
typeset -i sec=0
typeset -i totalDays=0
typeset -i totalHours=0
typeset -i totalMinutes=0
typeset -i totalSeconds=0

date -u +"%Y %j %H %M %S" | read year jDay hour min sec

(( totalDays = ($year - 1970)*365 + ($year - 1968)/4 + $jDay - 1 ))
(( totalHours = $totalDays*24 + $hour ))
(( totalMinutes = $totalHours*60 + $min ))
(( totalSeconds = $totalMinutes*60 + $sec ))

echo $totalSeconds
