Attempt to fix freebsd build after r287864

the chrono library there uses long long as the underlying chrono type, but
defines int64_t as long (or the other way around, I am not sure). In any case,
this caused the implicit conversion to not trigger. This should address that.

Also fix up the relevant unit test.
