Great, thanks for testing.

current-time-string is trivial: just call it, and see that the value
is reasonable.

format-time-string is not much harder, see its doc string.

decode-time can be tested by passing it what current-time returns, and
also the time-related info from file-attributes.

encode-time can be tested by passing it the result of decode-time.

In each case, please compare with the results of some older binary of
Emacs, as the differences could be subtle.

Thanks.
