Dearr all

I have access to login with system that shows more logs .

as we know <cat> command it if for show all the logs lines .
my question is to do command to see all the logs with time .
for example :
I want to see logs from 03:00:00 to 10:00:00 .
the command I use to see the normal log is :
cat catrx*/HCA/20081220
so where can I add the new command to see the time for logs between period time .
