Subject: [PATCH] Omit some (current-time) calls

* lisp/emacs-lisp/ert.el (ert-write-junit-test-summary-report):
* lisp/emacs-lisp/shortdoc.el (file):
* lisp/find-lisp.el (find-lisp-find-dired-insert-file):
* lisp/progmodes/hideif.el (hide-ifdefs):
* lisp/tar-mode.el (tar-subfile-save-buffer):
Prefer nil or omitted arg to (current-time) where this is better
or more-efficient.
