Version: 0.0~git20141101.0.1fdf08f-1
Severity: serious

Dear Maintainer,

For both me and the reproducible builds builder, the package fails one of its tests.

I don't know if this is filesystem variation (btrfs for me, tmpfs for
the builder), or if it's just non-deterministic... or if there's actually a bug.

Me:
   dh_auto_test -O--buildsystem=golang
	go test -v github.com/spf13/fsync
=== RUN TestSync
--- FAIL: TestSync (0.01s)
	fsync_test.go:136: modification time for "dst" is 2015-10-18 17:53:51.170102485 +0000 UTC, should be 2015-10-18 17:53:51.166102492 +0000 UTC.
FAIL
exit status 1
FAIL	github.com/spf13/fsync	0.010s
dh_auto_test: go test -v github.com/spf13/fsync returned exit code 1
