Probably because you're still redirecting the output you need...

How about this: Save it in a temp file then use that file.

Code:
#!/bin/bash
for I in {1}
do
        /usr/bin/time -f "%E"  ~/oblig1/oblig1a.sh
done 2> timefile

(       while IFS=":." read MIN SEC TENTH
        do
                printf " %s " "( ( $MIN * 60) * $SEC ) +"
        done

        echo "0" # Print the last number so it's ...+0.  Also, a newline.
) < timefile | bc

Also: "for I in {...}" is inefficient and prone to breaking when you run out of arguments. how about:

Code:
for ((I=0; I<10; I++))
do
...
done

keyarch

KEYARCH(1p)						User Contributed Perl Documentation					       KEYARCH(1p)

NAME

       keyarch - DNSSEC-Tools daemon to archive old KSK and ZSK keys

SYNOPSIS

	 keyarch [options] <keyrec_file | rollrec_file>

DESCRIPTION

       The keyarch program archives old KSK and ZSK keys.  Keys are considered old if they are revoked or obsolete.  Keys marked as either kskrev
       or zskrev are revoked; keys marked as either kskobs or zskobs are obsolete.  Archived keys are prefixed with the seconds-since-epoch as a
       means of distinguishing a zone's keys that have the same five digit number.

       If the required file argument is a keyrec file, then expired keys listed in that file are archived.  If the file argument is a rollrec
       file, the keyrec files of the zones in that file are checked for expired keys.

       If the -zone option is given, then only revoked and obsolete keys belonging to the specified zone will be archived.

       The archive directory is either zone-specific (listed in the zone's keyrec record in the zone's keyrec file) or the default archive
       directory given in the DNSSEC-Tools configuration file.

       The count of archived keys is given as the program's exit code.	Error exit codes are negative.

OPTIONS

       The following options are recognized:

       -zone zone_file
	   Name of the zone whose KSKs will be archived.  If this is not given, then all the zones defined in the rollrec file will be checked.

       -kskonly
	   Only archive KSK keys.

       -zskonly
	   Only archive ZSK keys.

       -dtconfig config_file
	   Name of an alternate DNSSEC-Tools configuration file to be processed.  If specified, this configuration file is used in place of the
	   normal DNSSEC-Tools configuration file not in addition to it.  Also, it will be handled prior to keyrec files, rollrec files, and
	   command-line options.

       -quiet
	   No output will be given.

       -verbose
	   Verbose output will be given.

       -help
	   Display a usage message.

       -Version
	   Displays the version information for keyarch and the DNSSEC-Tools package.

EXIT VALUES

       On success, keyarch's exit code is the number of keys archived.

       keyarch has a 0 exit code if the help message is given.

       keyarch has a negative exit code if an error is encountered.
