You don't say whether you are processing this line by line, or need to extract your bits from a multiline lump of data. You are also not at all clear as to which parts of the lines you wish to keep, and whether you want to capture them as 2 or 3 pieces.

This assumes that you processing line by line and want 3 pieces from each line.

if( $line =~ /^([^:]+): (.+) \((\d+) minutes ago\)$/ ) {
    my( $name, $text, $delay ) = ( $1, $2, $3 );
