could show that by posting a collection-status?

right, it shouldn't.

can you post a list of the files on the remote?

the man page could be more specific. time is given wrt. the backup date. it's 
only useful during restore or verify. eg.

restore from april fools day
 duplicity --time 2918/4/1 file://test/bkp /restore

restore from a week ago
 duplicity --time 1W file://test/bkp /restore

but generally it is not needed in your case as the default value when not given 
is 'now', meaning the latest backup avail.

the man page holds some details on the formatting of time
