Need your help

This is set to start on day 0 (sunday) at 1 second past midnight

"Timers": [
    {
      "Time": "00:00:01",
      "DayOfWeek": 0,
      "Commands": [

This is set to end same day at just before midnight,

{
      "Time": "23:59:59",
      "DayOfWeek": 0,
      "Commands": [

However, time commands like so 

At midnight Sunday it ran this is this order;

1st >> This ran first [TimedCommands] 
Running "23:59:59" timer

then 

2nd >> [TimedCommands] 
Running "00:00:01" timer

I am wondering why it ran the first one first and not later that day at the set time.
