Impossible to set date in 11.3.0?

[C. Scott Ananian]

A friend has 11.3.0 installed on his son's XO 1.5.  The kid complained
that the date was wrong on his XO, and he couldn't figure out how to
set it.  Indeed, the "Time and Date" control panel only has time zone
selection, and no sort of network time program seems to be included in
the build.  Was this an intentional omission?  How is the date
supposed to be set in 11.3?
