Extracting time from Crontab

Hi,

I am a beginner in shell scripting but I have a task to complete where I have to extract the time of script execution in human format so anyone can run the script and understand what script is running when in simple format. Let me illustrate what I mean:

Two scripts in crontab, for this illustration:

1 0 * * * /usr/bin/rotatelogs.pl
5 3,9,15,18,22 * * * /usr/scripts/backupDB.ksh

Now, how would I translate 0 in first line to say "00:01 AM" and same for second line translating it to "03:05 AM", "09:05 AM", "03:05 PM", " 06:05 PM", "10:05 PM".

Any help is greatly appreciated and if you think there is an excellent source to learn on the shell scripting, on the web or a book please advice.

Thanks in advance!!
HS
