touble with a time calculation

[longpole001]

hi richard , the main clock cant be stopped and needs to be a running test

the rollover from sec to mins is the issue as well as mins to hours

with the Set_Day= 0, Set_Hour= 0 ,Set_min= 0, Set_sec = 10

this code has that issue of when the clock roles over

the OT variables are used to display the OT clock
Days, Hours, Mins,Secs variables are the main clock
"Set_" varables are the time allowed

the OT clock is only enabled after the Set time is = > than the main clock

    if  OT_Days => Set_Day and OT_Hours => Set_Hour and OT_Minutes => Set_Min and OT_Seconds => Set_OT_Sec then OT_Enable = 1
 

   if OT_Enable = 1 THEN    
        if Days     >  Set_Day   then OT_Days    = Days  - Set_Day   
        if Hours    >  Set_Hour  then OT_Hours    = Hours - Set_Hour
        if Minutes  > Set_Min    then OT_Minutes = Minutes - Set_Min 
        if Seconds > Set_Sec   then OT_Seconds = Seconds - Set_Sec
       
     endif
