I would pick an interval that is a prime number, so that the exact second where the FLW, date, etc comes up varies slightly. So instead of 15, use 17 or 19. Most of my clocks do their alternate thing at 15 and 45 seconds, and it's predictably annoying, and annoyingly predictable. I'm gonna go back and recode that.
If you have other clocks in the room, then 15 seconds is probably OK; but if it's the only clock I would stretch it out closer to 30.
