Session scheduling/Start of day operation

Hello,

i played a bit around with the session scheduling feature; the settings "StartTime", "EndTime". I discovered (in the message logs), that Quickfix only suddenly stops the session when "EndTime" is reached, but does not send an logout to the remote FIX Engine.
When starting the session, quickfix initiates an login which is denied because the remote quickfix engine has reset the sequence numbers and sends me the message "Your session needs Start-of-day". I could set the ResetOnLogon flag, but this is not really an "start of day" operation; if i would logout during the day it would reset the sequence-numbers as well.
Why does quickfix don´t send an logout when the "EndTime" is reached ?. Ho would i implement a "Start-of-day" operation, only reset sequence numbers on "StartTime" ?.

Regards
Thomas
