I upgraded to Fedora 22 an hour ago and saw this bug with "ar" which happens everytime

Steps to Reproduce:

echo "void func(){}" > s.c
rm -f lib.a s.o
/usr/bin/gcc -c s.c
/usr/bin/ar rv lib.a s.o
/usr/bin/ar tv lib.a
/usr/bin/ls -l

Actual results:
/usr/bin/ar: creating lib.a
a - s.o
rw-r--r-- 0/0   1224 Jan  1 01:00 1970 s.o
total 16
-rw-r-----. 1 pas pas 1366 May 26 19:48 lib.a
-rw-r-----. 1 pas pas   14 May 26 19:48 s.c
-rw-r-----. 1 pas pas 1224 May 26 19:48 s.o

Expected results:
I'd expect to see the s.o file in lib.a have a time of 19:48

Additional info:
Using binutils-2.25-5.fc22.x86_64

I've put this with a priority of High, if it's my mistake then ignore me, but if it's a real bug it should be urgent.

Workaround
I'm actually using Makefiles so after I build a libaray, I'm using "make -t" which touches all the targets in the library with the current time
