Cron Entry

Hi folks,
I have got the following cron entry ...

08 30 * * * /mp1/scripts/test.sh > /mp1/scripts/test_logs.txt 2>&1

The problem is that instead of generating a new test_logs.txt file every time it keeps on appending the outputs to the test_logs.txt file. What is it that I am doing wrong here?

2nd position is hour, 30 will give error when quit cron list. it must be 1-24 only. Wonder it could run properly

apart from that, look correct in term of >

Sorry about that, the entry goes like 30 08 only ... put it there by mistake ...
