If your shell is ksh, your problem is resolved.

Download the following script : [url]days

In your script, add the following code :

Code:

. days

function difftimes {
   typeset dt1=$1
   typeset dt2=$2
   set $(echo $dt1 | tr ':-' '  ')
   unixtime $3 $2 $1 $4 $5 $6
   integer t1=unixtime
   set $(echo $dt2 | tr ':-' '  ')
   unixtime $3 $2 $1 $4 $5 $6
   integer t2=unixtime
   echo $((t2-t1))
}

The 'difftimes' function write to stdout the difference (seconds) between two dates:

Code:

ANA_ST="06-feb-2004 11:21:11" 
ANA_ED="06-feb-2004 11:23:17"
ANA_TI=$(difftimes "$ANA_ST" "$ANA_ED")  # result 126 (seconds)
