search on weblogic logs with date time ranges

Hi All,

The developers want me to search and capture the weblogic log, you know this big logs of htmls.

They want to me to have ranges on the date and time. Like

from "2010-01-20 14:04:46,186" to "2010-01-20 15:00:12,490"

I can only do this,
cat /usr/local/bea/logs_prod1/debug.log | grep 2010-01-20 | grep 0360068510 > file

The 0360068510 is the main key search on the ranges date/time above.

Please help, thank you for any comment you may add.

I'm afraid I don't know what a big log of HTMLs is, please provide an example of the input.
