Here's kind of an old chestnut...

The question is: How can you reliably printf() a time_t value?
What conversion spec should you use?

The answer seems to be: try stuff until the compiler doesn't warn.

Note that there is now %z for size_t, but there really should be a "Just do
the right thing - you're the compiler, you know what type the arg is, do
the right thing" spec.

It turns out that in my use case, %lu works, but how can you know?
Note, BTW, that another way to do it is to use %d and case the time_t value
to (int), but that seems kludgey.
