in reply to How long 'tween now and then?

If you can keep a tiny little data file around, you only need to figure out the epoch seconds for one invocation of the script. Just add (60 * 60 * 24) seconds to it once a day, and generate the new sleep value with a simple subtraction statement.

I'd do something like:

# run operation # get timestamp from file # add 60 * 60 * 24 to it # write new timestamp to file # subtract current seconds from timestamp # sleep for result seconds
