I would venture to say you aren't even making an effort.
I did a quick search for "Verilog digital clock code" and it came back with 628,000 results and the first 5 links have Verilog code to do exactly what you are asking.
Or perhaps your problem is not understanding modulo counting, which is how you count out seconds, minutes, and hours?.
I want to help, but this is blatant offloading of work. How are you going to get any better?
You need to know the following
1. You use the clock to generate a counter.
2. Based on clock speed a certain multiple will give you a second.
3. You can represent events that tick over to implement other counters. For example 60 seconds makes a minute. 60 minutes makes an hour and 24 hours make a day.
This is a very common university homework and is not difficult.
Show us what you have attempted to do so far.
If you are not comfortable with Verilog, then learn it first. This task will exercise you ability on how good you understand counters and implement counters with Verilog.
