A good standard date format is YYYY-MM-DD (the
ISO 8601
standard). Writing 'June' is okay, but you need to know English. But
of course any such conversion should probably be encapsulated in a
proc that produces pretty dates, and users should be able to change it.
Probably best to retrieve the date from the database just in one
single format (YYYY-MM-DD HH:MM:SS), and do any munging into the
pretty date using a Tcl proc. That is more flexible and more portable.
