+The `time' fields are normally displayed with the greatest
+precision their widths permit.
+This toggle reduces that precision until it wraps.
+It also illustrates the scaling those fields \fImight\fR experience
+automatically, which usually depends on how long the system runs.
+
+For example, if 'MMM:SS.hh' is shown, each ^E keystroke would change
+it to: 'MM:SS', 'Hours,MM', 'Days+Hours' and finally 'Weeks+Days'.
+
+Not all time fields are subject to the full range of such scaling.
