I have a flexible schedule now and can be ready at almost anytime if I know a document is coming (I monitor my email via iPhone, so I will see an alert when a project has arrived; then I will try to deal with it as soon as possible).

I generally work all day and some evenings (weekdays and weekends). 

Again, if I receive a notice that a document will be submitted at a certain time, I will try to be ready then.
