+          System time can be set by 'date -s DATE' and simply 'date DATE',
+          but formats of DATE string are different. 'date DATE' accepts
+          a rather weird MMDDhhmm[[YY]YY][.ss] format with completely
+          unnatural placement of year between minutes and seconds.
+          date -s (and other commands like touch -d) use more sensible
+          formats (for one, ISO format YYYY-MM-DD hh:mm:ss.ssssss).
+
+          With this option off, 'date DATE' is 'date -s DATE' support
+          the same format. With it on, 'date DATE' additionally supports
+          MMDDhhmm[[YY]YY][.ss] format.
