From perlfunc:

-M Script start time minus file modification time, in days. -A Same for access time. -C Same for inode change time

So, for 15 minutes you want any matching file where the return from -C is > than 15*60 / 86400:

while( glob '*' ) {
    if( -C() > 0.010416 ) {
        unlink $_;
    }
}

In the absence of evidence, opinion is indistinguishable from prejudice.
