Adding Seconds to Schedule Feeds

[TekieG]

Is it possible to add the seconds to the schedule feeds? I have a particular Kitty that will go to the feeder that comes out first and he runs fast while his brother takes his time, So we always try to set out feeders a maximum of 5 to 10 seconds apart so the kitty will go for his first, but since these are regular internal electronic clocks on the feeders, both feeders will eventually get out of sync within 2 days. Thanks!
