Nils,
Thanks for your reply. I have made a small bash-script with it and it 
works as expected. However, I also want the first line - which has the 
headers - also changed so that the first three headers are change to 
date and the next two to time. However, the script I made and expected 
to work doesn't. The script part with your solution works OK.
This is my script:
_______________________________________________________________
#!/bin/bash
#Simple program make the first 5 fields in a .csv-file into a date time 
format
echo "$1 en  $2"\n;
sed -e '1,1s/day,month,year/date/' -e '1s/hour,minute/time/' -e 
'2,$s/,/-/' -e '2,$s/,/-/' -e '2,$s/,/\ /' -e '2,$s/,/:/' -e 
'2,$s/,/:0,/' $1 > $2;
_____________________________________________________________
It doesn't give errors but line one is not changed. Perhaps you can see 
my error? In the result file line 1 is unchanged.
