Comment faire une soustraction de date?
Bonjour,

Comment faire une soustraction de dates en shell ??????

Smilie

j'ai 2 dates de la forme : DD/MM/YYYY HH:MM/SS

que j'aimerais soustraire, existe-t-il un format julian qui permette d'effectuer la soustraction ? ou bien faut il décomposer la date en DD, MM, YYYY etc, et soustraire chacune des unités ????

Quelqu'un peut-il m'aider ????

Merci
Smilie

How to make a substraction of dates
Sorry, sorry

So, I write my question again :

How can I manage to substract 2 dates with a script shell ?

The date format is :
DD/MM/YYYY HH(24):MI:SS


Is there a simple solution or should I write a complicated function ?

Thank you for your help
