+
+        Support higher-resolution time stamps (Bug#9000).
+
+        * calendar/time-date.el (with-decoded-time-value): New arg
+        PICO-SYMBOL in VARLIST.  It's optional, for backward compatibility.
+        (encode-time-value): New optional arg PICO.  New type 3.
+        (time-to-seconds) [!float-time]: Support the new picoseconds
+        component if it's used.
+        (seconds-to-time, time-subtract, time-add):
+        Support ps-resolution time stamps as well.
+
+        * emacs-lisp/timer.el (timer): New component psecs.  All uses changed.
+        (timerp): Timer vectors now have length 9, not 8.
+        (timer--time): Support new-style (4-part) time stamps.
+        (timer-next-integral-multiple-of-time): Time stamps now have
+        picosecond resolution, so take a bit more care about rounding.
+        (timer-relative-time, timer-inc-time): New optional arg psecs.
+        (timer-set-time-with-usecs): Set psecs to 0.
+        (timer--activate): Check psecs component, too.
+
+        * proced.el (proced-time-lessp): Support ps-resolution stamps.
