More control over fetchmail debug interval

[Dougie Nisbet <dougie@tbird2.homelan>]

At the moment I run fetchmail with 

	OPTIONS="--daemon 3600 --syslog"

in /etc/default/fetchmailrc. This works fine but I don't really need it 
checking mail overnight, making unecessary calls to my ISP. Is there a way 
that I could configure it to be a bit more specific about the times it checks?

I'm experimenting whether I can start fetchmail in background mode, but 
without a checking interval. If this is possible, perhaps I can set up a cron 
job that will run fetchmail hourly between, say, 9 to 5, which causes the 
background fetchmail to wake up and check the mail, and do nothing overnight.
