Changing your widget to the following will change the way the time
appears in forms:
def timeplain(field,value):
if value == None:
value = ''
elif 'strftime' in dir
(value): # These are
value = value.strftime('%H:%M') #
the
else:
# changed
value = str
(value) # lines
id = '%s_%s' % (field._tablename, field.name)
return INPUT(
_type='text',
_id=id,
_class='time_plain',
_name=field.name,
value=value,
requires=field.requires,
)
In other places where you generate output you can use strftime('%H:
%M') to format e.g.
timetable=db((db.timetable.day==weekday)&
(db.timetable.time>=nowtime)).select
(db.timetable.ALL,orderby=db.timetable.time,limitby=(0,6))
in view
{{=timetable.time.strftime("%H:%M")}}

associate the IS_TIME() validator with the field, so I put:
db.define_table('timetable',
db.Field('day', 'integer'),
db.Field('time', 'time', widget=timeplain, requires=IS_TIME()))
Do you have the web2py book? The PDF version is very reasonably priced
and extremely good. http://www.lulu.com/content/4968879 The codebase
has developed since it was published but because of web2py's backward
compatibility, everything in the book is still valid. Documentation on
the newer features is available on the web site e.g.

Sorry if I was a little rude. I was just quite excited to see a
question on the mailing list that I thought I could actually answer!
