David,

I'm on vacation, so rather short. This:

taskSpawn ("dhsDailyUpdate", 100, 8, 20000, dhsDailyUpdate)

(from an IOC's startup script) runs every day at 0:00 UT.

dhsDailyUpdate is a function in our FITS file writing device
support in this case, but I'd guess that it can be any non-private
function in any code that's loaded on the IOC.

(We had something similar before, you'll probably find it if
you search the tech-talk archive for taskSpawn)

HTH,
Aloha,
Maren
