It seems like 'dwgtitled' is the way to go.
dwgtitled - Indicates whether the current drawing has been named.(by the user)
0 Drawing has not been named
1 Drawing has been named
dbmod - Only tells you if the database is empty, has data in it, or a command has been called.
It is not a sure fire way to tell if the dwg has been saved.
acad-push-dbmod and acad-pop-dbmod seem like a way to add data to a dwg database and then reset the dbmod sysvar so the dwg acts as if it hasn't been modified since the last save.
I wasn't sure where to look for the Editting time. All I could get was the 'time' function and that looked like too much info.
Thanks for all the help guys,
