"lambda" is a shortcut way of defining a function with no name. The
example I copied happened to give the widget function a name. My
example was based on http://www.web2py.com/AlterEgo/default/show/170 -
check there to make sure what you've got is right.
putting widget=timeplain in the field definition is equivalent to
doing
db.timetable.time.widget = timeplain
outside the table definition.
It's a matter of readability as to which you prefer. Using the lambda
function to create the widget would be slightly less efficient if
there was more than one field that you wanted to use that widget,
because you'd need to define the lamda twice.

You can change the error message by using changing the validator
assigment to something like IS_TIME(error_message=T('must be
HH:MM!'))
This is on manual page 178. The T() is for translation.

I hope I explained this in my previous post, which crossed over with
you recent reply.
