Subject: Re: calculate diff of 2 date(s) 

is ist possible that subst only works for the initial create of a logbook entry? when I change/edit one of the parameter "Einsatzbegin" or "Einsatzende" the "Einsatzzeit" is not changed.

I found the solution in the forum :-)

subst Einsatzzeit = $shell(/usr/local/elog/diff.sh \"$Einsatzbeginn\" \"$Einsatzende\")

and diff.sh is

#!/bin/sh
#set -x
s1=$(date -d "$1" +%s)
s2=$(date -d "$2" +%s)
d=$(echo "($s2-$s1)/60"|bc -lq)
printf "%.0f Minuten" $d

hi

I have an elogsystem for documenting emergency services. I have a starttime and an endtime. Is it possible to calculate the diff between the 2 timestamps and convert it to minutes?

 

Attributes = Bereitschafts Kalender Woche, Bereitschafts Woche, Einsatzbeginn, Einsatzende, Einsatzzeit, Telefon Nummer, Station, Status, Problem 
Options Status= Offen{1}, Erledigt{2}, Geschlossen{3}

......

Type Einsatzbeginn = datetime
Type Einsatzende = datetime

....

Subst Einsatzzeit  = $shell(Einsatzende - Einsatzbeginn)
