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