Time Scripts

[Chezor]

Suppose i want a countdown of 1 hour. which will be repeated constantly after each countdown gets over. Like countdown of 10 secs is running constantly.
when i type. !ctime
it shows 10
when i type !ctime it shows 8 or 5 or the number which is being countdowned virtually in the script.

so actually i have seen mta argonath script which has fish contest script.
so there 1 hour time is running for each contest.
people fish there and after 1 hour is finished the person with biggest fish gets money.
so how do i create a countdown of 1 hour which keeps repeating again and again after every hour.

2] suppose everyone are fishing [ i can create fish script using $rand technique ]
if some person gets fish weighted 20kg
the other gets 19kg
and third gets 15kg
how can the person be given reward of cash after the particular countdown hour is over ?
its some complicated script but i need some help, and i know you there are the best scriptors.
