What is the failure, and why using format-time-string solves that?
That test doesn't fail for me.

Please _always_ accompany patches with rationale and the details of
the problem necessary to understand the patch and decide whether it is
the right solution for the problem.  Comments in the code explaining
why it does things that are not self-evident (like uses literal years
for some and format-time-string for others) is also a welcome habit.

Also, this patch lacks the commit log message.

Thanks.
